摘要:
Neutron diffraction measurements on the ordered fcc alloys FePd3, MnPt3, and Cr0.3Pt0.7support the existence of localized magnetic moments on the Pd and Pt atoms. The individual moments were determined by combining the difference in moment, based on reasonable assumptions about the magnetic form factors, with the total moment as determined from magnetization measurements. The results for FePd3are consistent with suggestions based on magnetization measurements; at 300°K Fe has a moment of 2.73±0.13 &mgr;Band Pd of 0.51±0.05 &mgr;B. In MnPt3at 77°K a small moment on the Pt is observed (0.17±0.04 &mgr;B), with most of the moment residing on the Mn (3.60±0.09 &mgr;B). At room temperature the magnetic ordering in Cr0.3Pt0.7is ferrimagnetic, with a Cr moment (if assumed equal on both Cr and Pt sites) of 2.56±0.10 &mgr;Band a Pt moment of 0.47±0.05 oppositely aligned.
