Název v původním jazyce

Development of magnetic order in the TbNi(Al,In) series and magnetocrystalline anisotropy in TbT X compounds

Popis výsledku v původním jazyce

We report on the magnetic structures in the TbNiAl1MINUS SIGN x Inx compounds as determined by powder neutron diffraction. These compounds belong to a large family of ternary rare-earth intermetallics crystallizing in the ZrNiAl-type hexagonal structure.All studied compounds order magnetically with magnetic structures characterized by k1 = (0,0,0) and k2 = ( 1 2 ,0, 1 2 ) propagation vectors and magnetic moments aligned along or perpendicular to the hexagonal c axis. The magnetocrystalline anisotropy changes from uniaxial in the In-poor compounds (x 0.4) to planar in the In-rich compounds (x 0.5). The change of magnetocrystalline anisotropy type is a consequence of the development of structural parameters in the studied series. The Tb moments are oriented along the c axis when the nearest Tb-Tb distances between the planes are large compared to those within the planes, whereas Tb moments lie within the basal planes in the opposite case. This picture relating the structural parameters
