Magnetic structure of Fe-substituted CoCr2O4 multiferroic thin films
Multiferroic materials in which multiple order phenomena coexist have been the subject of intense research over the past decade. Although single component multiferroic materials are rare, the research efforts in these systems are driven by the possibility to directly control magnetic order by electric fields through a robust magnetoelectric coupling. For a range of device applications, the integration of the material in a thin film is necessary, in which the reduced dimensionality and proximity effects can drastically alter the magnetic structure through interface phenomena and strain. In this proposal, we aim to investigate the magnetic structure of Fe-doped CoCr2O4 single component multiferroic thin films. The results will establish the magnetic ordering of the parent compound with different interface and strain scenarios and elucidate the mechanism leading to intrinsic exchange bias and magnetic compensation upon substitution. The results will be pivotal for understanding the magnetic behaviour upon cation substitution in a thin film multiferroic and provide the ground for further tuning and stabilization of the desired functional properties.
