在大阪大学用脉冲磁体测量了单晶DyCu稀土和非磁性过渡金属化合物的高场强磁化强度，最高可达60T。由于基态多轴自旋结构的自旋重排，沿[111]、[110]和[100]轴的磁化曲线呈现出多阶跃行为。对于[111]方向，观察到了具有四个变磁转变的磁化曲线的全貌，首次获得饱和磁矩为9.5µB。通过引入唯象假设，从磁化强度的相对值出发，提出了各相中可能的自旋结构。
High field magnetization measurements up to 60 T in a single crystalline DyCu rare earth and non-magnetic transition metal compound have been performed by using pulse magnets in Osaka University. The magnetization curves along [111], [110], and [100] axes show multistep behaviors due to spin rearrangement from the multiaxis spin structure of the ground state. For [111] directions, whole profile of magnetization curve with four metamagnetic transition is observed and the saturated moment is obtained to be 9.5 µ B for the first time. Possible spin structures in each phases are proposed from the relative value of the magnetization with introducing phenomenological assumptions.
