Abstract
Concentration dependences of the room temperature lattice constant and the Néel temperature of Mn100-xRhx (19≦x≦30) ordered alloys were investigated. The room temperature lattice constant becomes larger with increasing x. The Néel temperature also increases with the increase of x, and the high Néel temperature is not explained by an exchange interaction as a function of the Mn-Mn distance, but by the number of 3d electrons in the Mn site. Associated with spin fluctuations, the paramagnetic susceptibility increases with increasing temperature and shows a tendency to be saturated.
