摘要

在[公式：见正文]中观察到了零磁场下与温度相关的弱顺磁性电感峰，其中只有少量铁磁性杂质。铁磁磁滞回线以及零磁场冷却和场冷却过程之间的磁矩分裂表明样品具有铁磁性。顺磁类电感峰高与磁滞回线的剩磁矩成正比。高分辨率透射电子显微镜图像支持所观察到的铁磁性特征源于晶格畸变。这些结果表明，随温度变化的弱顺磁样电感峰源于弱晶格畸变和/或超顺磁性。

On the Paramagnetic-Like Susceptibility Peaks at Zero Magnetic Field in $\hbox{WSe}_{2-x}\hbox{Te}_{x}$ Single Crystals

A weakly temperature-dependent paramagnetic-like susceptibility peak at zero magnetic field is observed in $\hbox{WSe}_{2-x}\hbox{Te}_{x}$ with only marginal amount of ferromagnetic impurities. The ferromagnetic hysteresis loop and the magnetic moment splitting between zero-field-cooled and field-cooled processes indicate ferromagnetism in the samples. The paramagnetic-like susceptibility peak height is proportional to the remanent magnetic moment of hysteresis loops. High-resolution transmission electron microscope image supports that the observed ferromagnetic feature originates from lattice distortion. These results imply that the weakly temperature-dependent paramagnetic-like susceptibility peak originates from weak lattice distortion and/or superparamagnetism.
