By studying systems with one-, two-, and three-dimensional magnetic modulations, the research provided new insights into the coupling mechanisms that govern their magnetic behavior.<\/p>\n\n\n\n<p>In&nbsp;<strong>Fe\/MgO multilayers<\/strong>, interlayer exchange coupling through spin-polarized tunneling was used to achieve and control&nbsp;<strong>antiferromagnetic ordering<\/strong>, with coupling strength varying as a function of layer number and temperature. In&nbsp;<strong>two-dimensional metamaterials<\/strong>, arrays of magnetic \u201cmesospins\u201d demonstrated transitions between static and dynamic magnetic states, where lattice geometry and element size dictated the emergent magnetic textures. Finally, in&nbsp;<strong>amorphous CoAlZr and FeZr alloys<\/strong>, structural disorder and composition fluctuations were found to produce&nbsp;<strong>competing magnetic anisotropies<\/strong>, as revealed through off-specular scattering and low-temperature measurements.<\/p>\n\n\n\n<p>Together, these studies deepened the understanding of&nbsp;<strong>magnetic coupling, emergent order, and structural effects<\/strong>&nbsp;in complex materials, paving the way for tailored&nbsp;<strong>magnetic metamaterials and disordered systems<\/strong>&nbsp;with tunable properties for future spintronic and energy applications.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>PhD: Nanny Strandqvist, Uppsala University (2022)<\/p>\n","protected":false},"featured_media":0,"template":"","project_category":[50],"research_theme":[39],"class_list":["post-980","project","type-project","status-publish","hentry","project_category-former","research_theme-basic-chemistry-physics"],"acf":[],"_links":{"self":[{"href":"https:\/\/r8993.hemsida.eu\/swedness\/wp-json\/wp\/v2\/project\/980","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/r8993.hemsida.eu\/swedness\/wp-json\/wp\/v2\/project"}],"about":[{"href":"https:\/\/r8993.hemsida.eu\/swedness\/wp-json\/wp\/v2\/types\/project"}],"version-history":[{"count":1,"href":"https:\/\/r8993.hemsida.eu\/swedness\/wp-json\/wp\/v2\/project\/980\/revisions"}],"predecessor-version":[{"id":981,"href":"https:\/\/r8993.hemsida.eu\/swedness\/wp-json\/wp\/v2\/project\/980\/revisions\/981"}],"wp:attachment":[{"href":"https:\/\/r8993.hemsida.eu\/swedness\/wp-json\/wp\/v2\/media?parent=980"}],"wp:term":[{"taxonomy":"project_category","embeddable":true,"href":"https:\/\/r8993.hemsida.eu\/swedness\/wp-json\/wp\/v2\/project_category?post=980"},{"taxonomy":"research_theme","embeddable":true,"href":"https:\/\/r8993.hemsida.eu\/swedness\/wp-json\/wp\/v2\/research_theme?post=980"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
