Magnetism of CoFe2O4 ultrathin films on MgAl2O4 driven by epitaxial strain. Gatel, C., Warot-Fonrose, B., Matzen, S., & Moussy, J. Applied Physics Letters, 103(9):092405, August, 2013. WOS:000323846900033

We report on the correlations between magnetic anisotropy and strain state in CoFe2O4 ultrathin films grown on MgAl2O4(100) and MgAl2O4(111) substrates. By local strain analysis using the geometric phase method, a significant in-plane compressive strain is observed for the (001) orientation while a full relaxation is detected for the (111) orientation. The relaxation process in CoFe2O4(111) layers induces interface dislocations and a large amount of antiphase boundaries while a pseudomorphic growth is observed for the (001) direction, decreasing significantly the density of antiphase boundaries. By comparing the magnetoelastic energy terms, the correlation between strain state and resultant magnetization is discussed. (C) 2013 AIP Publishing LLC.
