For low gallium content, domains with the magnetization lying in the film plane and domain walls separating micrometric areas are observed. Above x ≈ 20, the magnetic contrast shows a fine corrugation, ranging from 300 to 900 nm, suggesting a ripple substructure with a periodic oscillation of the magnetization. We discuss the presence of a random magnetic anisotropy contribution, that superimposed to the cubic coherent anisotropy, is able to break the uniform orientation of the magnetization. The origin of that random anisotropy is attributed to several factors: coexistence of crystal phases in the films, inhomogeneous distribution of both internal strain and Ga–Ga next nearest neighbor pairs and interface magnetic anisotropy due to the Fe–O bond. 000131175 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E10-17D$$9info:eu-repo/grantAgreement/ES/MICINN/MAT2015-66726-R$$9info:eu-repo/grantAgreement/ES/MINECO/BES-2016-076482 000131175 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000131175 590__ $$a2.993$$b2020 000131175 591__ $$aPHYSICS, CONDENSED MATTER$$b33 / 69 = 0.478$$c2020$$dQ2$$eT2 000131175 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b188 / 333 = 0.565$$c2020$$dQ3$$eT2 000131175 592__ $$a0.665$$b2020 000131175 593__ $$aElectronic, Optical and Magnetic Materials$$c2020$$dQ2 000131175 593__ $$aCondensed Matter Physics$$c2020$$dQ2 000131175 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000131175 700__ $$0(orcid)0000-0003-4079-2658$$aProietti, M.G.$$uUniversidad de Zaragoza 000131175 700__ $$0(orcid)0000-0002-2624-6004$$aArnaudas, J.I.$$uUniversidad de Zaragoza 000131175 700__ $$0(orcid)0000-0003-1930-1455$$aCiria, M.$$uUniversidad de Zaragoza 000131175 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
