摘要：

We have studied growth conditions and structural and magnetic properties of FePd ferromagnetic layers deposited on (001) CdZnTe semiconductors. By using Au and Pd as buffer layers between the II-VI compound and the FePd, a two dimensional growth of the alloy is obtained. The alloy is well chemically ordered with the L1(0) tetragonal structure and is perpendicularly magnetized with a perpendicular magnetic anisotropy constant of about 6.6.10(6) erg cm(-3). Magnetic force microscopy images showed the perpendicular magnetic configuration with up and down domains whose size is about 70 nm. The results compare favorably with FePd layers elaborated in the same run on an MgO substrate. (C) 1999 American Institute of Physics. [S0003- 6951(99)01744-1].
