Abstract

TbFeCo is an important MO media material and even a candidate for hybrid recording. Our experimental results show that two magnetic phases can co-exist in TbFeCo films with orthogonal easy axes, which are along the film plane or out-of-plane. Suggested by the hystersis curves measured by the extraordinary Hall effect (EHE) and vibrated sample magnetometer (VSM), there is a transition region between domains with different easy axes of magnetization. The exchange coupling in between acts as a biased field, which may migrate the magnetic switching field for each loop.
