CdGd_2(WO_4)_4单晶的磁性研究

Study on Magnetic Properties of CdGd_2(WO_4)_4 Single Crystal

磁化曲线σ-H和电子自旋共振谱(ESR)表明钨酸钆镉(CdGd_2(WO_4)_4,简称CGW)单晶具有磁各向异性.当外磁场等于零或者较小时,难磁化方向的磁化强度为负值,利用各向异性场对此进行了解释,并由ESR谱计算出了各向异性场.

The magnetic properties of the cadmium gadolinium tungstate [CdGd2 （WO4）4,CGW] single crystal were studied by magnetic measurement （σ-H） and electron spin resonance （ESR） experiments. The magnetic anisotropy of the CGW is showed from the experiments. It was discussed by anisotropy field that the parallel magnetization to the c-axis is negative when H=0. The anisotropy field BK was calculated according to ESR experiment.
