在三砷化铕中发现了一种新的不通约磁相，它属于一类新型层状半金属化合物。这种不相称相位在 T N= 11.30 K 以下发展，随后在 T L= 10.26 K 处锁定过渡到相称相位。虽然这种情况发生在区域边界波矢量处，但这种过渡几乎是连续的。我们提出了根据孤子晶格模型对调制矢量的非常平滑的温度依赖性的解释。
A new incommensurate magnetic phase has been found in europium triarsenide which belongs to a novel class of layered semimetallic compounds. This incommensurate phase develops below T N= 11.30 K and is followed by a lock-in transition to a commensurate phase at T L= 10.26 K. Although this happens at a zone-boundary wave vector, the transition is nearly continuous. We propose an interpretation of the very smooth temperature dependence of the modulation vector in terms of the soliton lattice model.
