论文摘要
通过高温溶液的生长技术合成了Shastry-Sutherland磁性半导体Band2ZNS5的单晶。物理特性的特征是粉末和单晶X射线衍射，温度和田间依赖性磁化以及温度依赖性的特异性热测量值。 Band2ZNS5在2.9 K处施加抗磁性，磁矩主要在AB平面内对齐。磁等温测量结果显示[110]方向的〜15 KOE的元磁过渡，[100]方向〜21 KOE。估计的磁熵提示每个ND离子的双基态。
Single crystals of a Shastry-Sutherland magnetic semiconductor, BaNd2ZnS5, were synthesized through a high-temperature solution growth technique. Physical properties were characterized by powder and single crystal x-ray diffraction, temperature- and field-dependent magnetization, and temperature-dependent specific heat measurements. BaNd2ZnS5 orders antiferromagnetically at 2.9 K, with magnetic moments primarily aligned within the ab-plane. Magnetic isothermal measurements show metamagnetic transitions at ~ 15 kOe for the [110] direction and ~ 21 kOe for the [100] direction. Estimated magnetic entropy suggests a double ground state for each Nd ion.
