Abstract
The magnetic properties of Co-P films with different structure depended on the temperature were investigated. The Co-P films happen to the transition from the weak ferromagnetic to the strong ferromagnetic at lower temperature. At higher temperature, the Co phase transformation from HCP to FCC crystal structure results in a sudden change of the magnetization of the nanocrystalline Co-P films. For the amorphous Co-P films, the occurrence of the crystallization at 610 K leads to a magnetization transition. The first-principles calculations shows that the intense exchange coupling of Co-Co and Co-P atoms from the Co and the Co2P phase contributes to the magnetic property.
