Its appearance is explained in terms of moderate coupling between twin variants having strong uniaxial magnetocrystalline anisotropies directed orthogonally when the intertwin exchange field is comparable with the anisotropy field. This finding paves the way to increase the order of magnetic anisotropy in a many-component system while keeping the value of the anisotropy field by tuning the intercomponent exchange strength and can be extended to exchange-coupled multilayers and arrays of nanoelements.<\/jats:p>","DOI":"10.1063\/5.0162561","type":"journal-article","created":{"date-parts":[[2023,12,22]],"date-time":"2023-12-22T20:38:00Z","timestamp":1703277480000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":3,"title":["Giant four-fold magnetic anisotropy in nanotwinned NiMnGa epitaxial films"],"prefix":"10.1063","volume":"11","author":[{"given":"Pavlo V.","family":"Bondarenko","sequence":"first","affiliation":[{"name":"Institute of Magnetism NAS of Ukraine and MES of Ukraine 1 , 36-B Vernadsky Blvd., 03142 Kyiv, Ukraine"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2186-1382","authenticated-orcid":false,"given":"Julia","family":"Kharlan","sequence":"additional","affiliation":[{"name":"Institute of Magnetism NAS of Ukraine and MES of Ukraine 1 , 36-B Vernadsky Blvd., 03142 Kyiv, Ukraine"},{"name":"Faculty of Physics, Adam Mickiewicz University in Poznan 3 , Umultowska 85, 61\u2013614 Poznan, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6407-5365","authenticated-orcid":false,"given":"Sergey A.","family":"Bunyaev","sequence":"additional","affiliation":[{"name":"Institute of Physics for Advanced Materials, Nanotechnology and Photonics (IFIMUP)\/Department of Physics and Astronomy, Faculty of Sciences, University of Porto 4 , 4169-007 Porto, Portugal"}]},{"given":"Olga","family":"Salyuk","sequence":"additional","affiliation":[{"name":"Institute of Magnetism NAS of Ukraine and MES of Ukraine 1 , 36-B Vernadsky Blvd., 03142 Kyiv, Ukraine"},{"name":"National Technical University of Ukraine \u201cIgor Sikorsky Kyiv Polytechnic Institute 2 ,\u201d 37 Peremohy Ave., 03056 Kyiv, Ukraine"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-6721-6401","authenticated-orcid":false,"given":"Ivan R.","family":"Aseguinolaza","sequence":"additional","affiliation":[{"name":"University of the Basque Country (UPV\/EHU) 5 , Bilbao 48080, Spain"}]},{"given":"Jose M.","family":"Barandiaran","sequence":"additional","affiliation":[{"name":"University of the Basque Country (UPV\/EHU) 5 , Bilbao 48080, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7081-581X","authenticated-orcid":false,"given":"Gleb N.","family":"Kakazei","sequence":"additional","affiliation":[{"name":"Institute of Physics for Advanced Materials, Nanotechnology and Photonics (IFIMUP)\/Department of Physics and Astronomy, Faculty of Sciences, University of Porto 4 , 4169-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0933-9372","authenticated-orcid":false,"given":"Volodymyr","family":"Chernenko","sequence":"additional","affiliation":[{"name":"University of the Basque Country (UPV\/EHU) 5 , Bilbao 48080, Spain"},{"name":"Basque Center for Materials, Applications and Nanostructure, BCMaterials 6 , Leioa 48940, Spain"},{"name":"Ikerbasque, Basque Foundation for Science 7 , Bilbao 48009, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7550-3978","authenticated-orcid":false,"given":"Vladimir O.","family":"Golub","sequence":"additional","affiliation":[{"name":"Institute of Magnetism NAS of Ukraine and MES of Ukraine 1 , 36-B Vernadsky Blvd., 03142 Kyiv, Ukraine"}]}],"member":"317","published-online":{"date-parts":[[2023,12,22]]},"reference":[{"key":"2023122220375600000_c1","doi-asserted-by":"publisher","first-page":"014203","DOI":"10.1103\/physrevb.79.014203","volume":"79","year":"2009","journal-title":"Phys.
