We investigate the cubic magneto-optic Kerr effect (CMOKE) in thin films of cubic crystal structures. CMOKE is proportional to third order in magnetization (∝M3) and was recently observed in Ni(111) thin films with 45∘ incidence of light [1]. At this angle of incidence, no CMOKE could be observed for (001)-oriented Ni thin films so far. However, we could observe a distinct CMOKE signal in Ni(001) at grazing incidence. Similar behaviour is found in other materials with (001)-oriented cubic crystal structure, indicating that grazing-incidence CMOKE is a more general feature of this crystal orientation. In this contribution, we present first experimental results of grazing-incidence CMOKE and discuss the incidence-angle dependence of CMOKE for different materials and crystal orientations. Our findings open new possibilities for CMOKE-based characterization of materials with (001)-oriented crystal structures.
