Abstract

We have performed a systematic Hall measurement on the GaMnAs ferromagnetic films. The angular dependences of the Hall effects were obtained by changing the magnetic field angle in two different crystal planes [i.e., (001) and (110)]. The in-plane and out-of-plane anisotropy fields were obtained by analyzing the angular dependence of planar Hall resistance and anomalous Hall resistance based on the magnetic free energy model. While the cubic anisotropy fields both for in-plane and out-of-plane showed strong temperature dependence, the uniaxial anisotropy fields were insensitive to the temperature.
