The systematic magnetic properties in the zircon‐type GdVO₄ single crystal are reported herein. Antiferromagnetic (AFM)‐ordered GdVO₄ single crystal presents an upturn below 150 K in the H/M curves. With the decreasing of the field, the upturn behavior enhances which is probably due to spin‐glass‐like behavior that exists in this system. The short‐range order related spin‐glass‐like feature is also observed in the time‐dependent magnetization relaxation. Furthermore, the M (T) and M (H) curves of the single crystal reveal an anisotropic character with two different spin‐flop transitions along the c axis (1 T) and the a, b axes (1.7 T). Combining the high‐frequency electron spin resonance (ESR) measurement and the structure analysis, the main cause of the magnetic anisotropy can be explained as the contribution of the exchange coupling anisotropy due to the asymmetrical environment of the Gd³⁺ ions.

GdVO4单晶中的自旋玻璃像冻结行为和磁各向异性

本文报道了锆石型GdVO ₄单晶的系统磁性。反铁磁（AFM）排序的GdVO ₄单晶在H / M曲线中呈现低于150 K的向上趋势。随着场的减小，上倾行为增强，这可能是由于该系统中存在类似自旋玻璃的行为。在与时间有关的磁化弛豫中也观察到了与短程相关的自旋玻璃状特征。此外，单晶的M（T）和M（H）曲线还显示出各向异性特征，沿着c轴具有两个不同的自旋-跃迁跃迁轴（1 T）和a，b轴（1.7 T）。结合高频电子自旋共振（ESR）测量和结构分析，磁各向异性的主要原因可以解释为由于Gd ³⁺离子的不对称环境引起的交换耦合各向异性的贡献。
