Spin Modulation Wave in Giant Magnetic Moment Systems PdCo and PtCo Alloys

抄録

Susceptibility and neutron scattering measurements were performed for the giant magnetic moment systems PdCo and PtCo alloys. Short range order of spin modulation wave was observed on the ferromagnetic spin alignment. The results were compared with those observed for other giant magnetic moment systems PdFe and PtFe alloys. A big difference exists for a response to an applied magnetic field probably due to a difference of magnetization easy axes in these systems. A hardness of the saturation magnetization of PdCo alloy would be ascribed to a complex magnetic structure of this system.
