Abstract

KNi(PO3)3 was successfully synthesized by solid-state method and the magnetic properties were characterized. The crystal structure of KNi(PO3)3 belongs to trigonal crystal system with space group R3, where Ni2+ ions form the distorted honeycomb-lattice within the ab-plane stacking in the “ABAB” type fashion along the c-axis. Magnetization measurements reveal the presence of antiferromagnetic (AFM) interaction with Curie Weiss (CW) temperature θCW =  − 12.905 K but without long-range magnetic order down to 2 K. Notably, the CW fitted effective moment µeff = 3.35µB and saturated magnetization MS = 2μB/Ni2+ at 2 K support KNi(PO3)3 as an S = 1 spin system. Intriguingly, the zero-field specific heat exhibits a broad peak maximized at ~ 2.5 K indicating the onset of short-range spin correlation between Ni2+ ions, while the integrated magnetic entropy (Smag) is close to the expected Rln3 for S = 1 system, indicative of large spin fluctuation below 2 K driven by spin frustration.

挫折S = 1磁体KNi(PO3)的合成、晶体结构和磁性表征
采用固相法成功合成了KNi(PO3)3,并对其磁性进行了表征。KNi(PO3)3的晶体结构属于空间群为R3的三角晶体体系,其中Ni2+离子在ab平面内沿c轴呈“ABAB”型堆叠形成扭曲的蜂窝状晶格。磁化测量结果表明,在居里魏斯温度θCW =−12.905 K时存在反铁磁相互作用,但在2 K以下没有长程磁序。值得注意的是,连续波拟合的有效矩μ eff = 3.35 μB,饱和磁化MS = 2μB/Ni2+在2k下支持KNi(PO3)3为S = 1自旋体系。有趣的是,零场比热在~ 2.5 K处表现出一个宽峰,表明Ni2+离子之间开始了短程自旋相关,而积分磁熵(Smag)接近S = 1系统的预期Rln3,表明自旋受挫驱动的自旋涨落在2 K以下。
