We then systematically determine and analyse solutions to these equilibrium equations under various canonical boundary conditions. We also determine the stability of the equilibrium solutions. Comparing our findings with the well-studied Euler\u2019s elastica provides insights into the magnetic effects on the deformation behaviour of elastic ribbons. Our analysis contributes to a deeper understanding of the interplay between magnetisation and the mechanical response of planar ferromagnetic structures, and offers valuable insights for both theoretical and practical applications.<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('10','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_10\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"fas fa-globe\"><\/i><a class=\"tp_pub_list\" href=\"http:\/\/dx.doi.org\/10.1007\/s10659-024-10100-w\" title=\"http:\/\/dx.doi.org\/10.1007\/s10659-024-10100-w\" target=\"_blank\">http:\/\/dx.doi.org\/10.1007\/s10659-024-10100-w<\/a><\/li><li><i class=\"ai ai-doi\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/dx.doi.org\/10.1007\/s10659-024-10100-w\" title=\"Follow DOI:10.1007\/s10659-024-10100-w\" target=\"_blank\">doi:10.1007\/s10659-024-10100-w<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('10','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_article\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\"> Venkatraman, Raghavendra;  Dabade, Vivekanand;  James, Richard D.<\/p><p class=\"tp_pub_title\"><a class=\"tp_title_link\" onclick=\"teachpress_pub_showhide('3','tp_links')\" style=\"cursor:pointer;\">Bounds on the Energy of a Soft Cubic Ferromagnet with Large Magnetostriction<\/a> <span class=\"tp_pub_type tp_  article\">Journal Article<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_in\">In: <\/span><span class=\"tp_pub_additional_journal\">Journal of Nonlinear Science, <\/span><span class=\"tp_pub_additional_volume\">vol. 30, <\/span><span class=\"tp_pub_additional_number\">no. 6, <\/span><span class=\"tp_pub_additional_pages\">pp. 3367\u20133388, <\/span><span class=\"tp_pub_additional_year\">2020<\/span>, <span class=\"tp_pub_additional_issn\">ISSN: 1432-1467<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_abstract_link\"><a id=\"tp_abstract_sh_3\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('3','tp_abstract')\" title=\"Show abstract\" style=\"cursor:pointer;\">Abstract<\/a><\/span> | <span class=\"tp_resource_link\"><a id=\"tp_links_sh_3\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('3','tp_links')\" title=\"Show links and resources\" style=\"cursor:pointer;\">Links<\/a><\/span> | <span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_3\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('3','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_3\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@article{Venkatraman2020,<br \/>\r\ntitle = {Bounds on the Energy of a Soft Cubic Ferromagnet with Large Magnetostriction},<br \/>\r\nauthor = {Raghavendra Venkatraman and Vivekanand Dabade and Richard D.

The sample synthesized in the lab exhibits a coercivity of 1220 Oe and an energy product of up to 9 MGOe. The mechanism of the strained-wire method is analyzed based on scanning-transmission-electron-microscopy characterizations of samples with different strains. We observe a strain-induced recrystallization of \ud835\udefc\u2032\u2032\u2212Fe16\u2062N2 samples at a low annealing temperature (150\u2009\u00b0C). We demonstrate that this strained-wire method can be used on \ud835\udefc\u2032\u2032\u2212Fe16\u2062N2 samples to increase the \ud835\udefc\u2032\u2032\u2212Fe16\u2062N2 phase-volume ratio and to fine-tune its microstructure at a low temperature. Some further characterization results are also included in this paper. The physics of the influence of tensile stress on the martensitic phase transition is discussed.<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('8','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_8\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"fas fa-globe\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/link.aps.org\/doi\/10.1103\/PhysRevApplied.6.024013\" title=\"https:\/\/link.aps.org\/doi\/10.1103\/PhysRevApplied.6.024013\" target=\"_blank\">https:\/\/link.aps.org\/doi\/10.1103\/PhysRevApplied.6.024013<\/a><\/li><li><i class=\"ai ai-doi\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/dx.doi.org\/10.1103\/PhysRevApplied.6.024013\" title=\"Follow DOI:10.1103\/PhysRevApplied.6.024013\" target=\"_blank\">doi:10.1103\/PhysRevApplied.6.024013<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('8','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_article\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\"> Dabade, Vivekanand;  Marath, Navaneeth\u00a0K.;  Subramanian, Ganesh<\/p><p class=\"tp_pub_title\"><a class=\"tp_title_link\" onclick=\"teachpress_pub_showhide('9','tp_links')\" style=\"cursor:pointer;\">The effect of inertia on the orientation dynamics of anisotropic particles in simple shear flow<\/a> <span class=\"tp_pub_type tp_  article\">Journal Article<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_in\">In: <\/span><span class=\"tp_pub_additional_journal\">Journal of Fluid Mechanics, <\/span><span class=\"tp_pub_additional_volume\">vol. 791, <\/span><span class=\"tp_pub_additional_pages\">pp. 631\u2013703, <\/span><span class=\"tp_pub_additional_year\">2016<\/span>, <span class=\"tp_pub_additional_issn\">ISSN: 1469-7645<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_resource_link\"><a id=\"tp_links_sh_9\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('9','tp_links')\" title=\"Show links and resources\" style=\"cursor:pointer;\">Links<\/a><\/span> | <span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_9\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('9','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_9\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@article{Dabade2016,<br \/>\r\ntitle = {The effect of inertia on the orientation dynamics of anisotropic particles in simple shear flow},<br \/>\r\nauthor = {Vivekanand Dabade and Navaneeth\u00a0K.
