Abstract

Ferromagnetic In _0.88Mn _0.12As films were grown on In _0.70Al _0.30As/AlSb/GaAs hybrid substrates by low-temperature molecular beam epitaxy. The built-in compressive strain leads to an in-plane easy axis of magnetization. Detailed studies of magnetic anisotropy by direct SQUID magnetization measurements, by ferromagnetic resonance measurements, and by the planar Hall effect unambiguously show the existence of both uniaxial and cubic anisotropy in the layer plane, similar to that observed previously in GaMnAs. However, at low temperature the in-plane easy axis of InMnAs is along the 〈110〉 direction, in contrast to the 〈100〉 direction observed in GaMnAs layers. © 2005 American Institute of Physics.
