Solid-state synthesis, structural and magnetic properties of CoPd films

The results of the investigation of the structural and magnetic properties of CoPd films with equiatomic composition have been presented. The films have been synthesized by vacuum annealing of polycrystalline Pd/Co and epitaxial Pd/$\alpha$-Сo(110) and Pd/$\beta$-Co(001) bilayer samples. It has been shown that, for all samples, the annealing to 400$^\circ$C does not lead to the mixing of layers and the formation of compounds. A further increase in the annealing temperature results in the formation of a disordered CoPd phase at the Pd/Co interface, which is fully completed after annealing at 650$^\circ$C. The epitaxial relationships between the disordered CoPd phase and the MgO(001) substrate are determined as follows: CoPd(110)$\langle\bar111\rangle$||MgO(001)$\langle$100$\rangle$ и CoPd(001)[100]||MgO(001)[100].
