7.2.5.2.3 Magnetic structure

Abstract

This chapter deals with magnetic structure of rare earth magnetic alloys. The magnetic moments determined by neutron diffraction measurements on R2Fe17Ax compounds and the calculated moments in some nitrides and carbides are tabulated. The magnitude of the rare-earth magnetic moments derived from neutron studies at 4.2 K are very close (within 5%) to the free-ion values. The total magnetization in case of Y2Fe17C1.0 is 38.4 μB/f.u.at 4.2 K, which is higher than that obtained by high-field measurements at the same temperature. The local magnetic moments in Y2Fe17Nx have been calculated as function of the unit-cell volume using the tight-binding LMTO-ASA method. Temperature dependence of the neutron depolarization, 1-Dyy in Tm2Fe17C0.4 around the magnetic ordering temperature is shown.
