我们报道了用提拉法生长对映体单晶以及基于电阻率、比热和磁化强度测量的单轴手性磁体的磁性。磁化率出现峰值，比热出现a型反常。随后，在电阻率、比热和磁化率中观察到了一级磁化转变。此外，我们还观察到了一个新的磁相变，这是以前没有报道过的，在和之间。我们在低温磁相中观察到了多个平台，并构建了一个非平凡的磁相图，这是该系统中竞争相互作用的结果。此外，我们还观察到横向磁阻的面内各向异性的增加和减少，这与磁结构的变化有关。
We report on the enantiopure single-crystal growth using the Czochralski method and the magnetic properties of the Nd-based monoaxial chiral magnetbased on electrical resistivity, specific heat, and magnetization measurements. A peak in the magnetic susceptibility and a-type anomaly in the specific heat are observed at. Successively, a first-order magnetic transition atis observed in the electrical resistivity, specific heat, and magnetic susceptibility. In addition, we observed a new magnetic phase transition, which has previously not been reported, atbetweenand. We observed multiple plateaus in the low-temperature magnetic phase and constructed a nontrivial magnetic phase diagram, which results from the competitive interactions in this system. Furthermore, we observed an increase and decrease in the in-plane anisotropy in the transverse magnetoresistance, which is related to the change in the magnetic structure.
