摘要：

The effects of substitution of Sc and Y for Tb on the magnetism of TbMn2, which is helimagnetic with a large Mn moment, were investigated by magnetization, thermal expansion and NMR measurements. The substitution of Sc for Tb reduces the lattice constant and collapses the Mn moment, resulting in the change of magnetic structure to ferromagnetism. The signal from nonmagnetic Mn atoms was detected by NMR. The substitution of Y for Tb, which expands the lattice, does not give any drastic change in magnetic properties. Factors of determining the stability of Mn moments and the effects of frustrative magnetic interactions on the magnetic structure are discussed. © 1990, THE PHYSICAL SOCIETY OF JAPAN.
