Magnetic field dependent cycloidal rotation in pristine and Ge doped CoCr${}_2$O${}_4$

N Ortiz Hernandez, S Parchenko, J R L Mardegan +11

We report a soft x-ray resonant magnetic scattering study of the spin configuration in multiferroic thin films of Co${}_{0.975}$Ge${}_{0.025}$Cr${}_2$O${}_4$ (Ge-CCO) and CoCr${}_2$O${}_4$ (CC…
