摘要

•Investigation of magnetic properties of GaMnAsP films with two different thicknesses.•The Curie temperature was higher in thicker GaMnAsP layer.•Annealing increases the Curie temperature of GaMnAsP layers.•The out-of-plane magnetic anisotropy becames stronger after annealing.•3-D magnetic anisotropy energy diagrams show easy axes of GaMnAsP films.
