Single crystals of NdVO4 were grown by the Czochralski method under ambient pressure in a nitrogen atmosphere. Obtained crystals were transparent with strong violet coloring. Temperature and angular dependences of electron paramagnetic resonance (EPR) spectra of the samples in the 3–103 K temperature range were analyzed applying Dyson like lineshape typically used for concentrated magnetic system. EPR-NMR program was used to find local symmetry and spin-Hamiltonian parameters of neodymium ions.

浓缩NdVO4单晶系的EPR特性

NdVO4 单晶是在氮气氛中在环境压力下通过直拉法生长的。得到的晶体是透明的，带有强烈的紫罗兰色。应用通常用于集中磁系统的戴森线形分析了样品在 3-103 K 温度范围内的电子顺磁共振 (EPR) 光谱的温度和角度依赖性。EPR-NMR 程序用于寻找钕离子的局部对称性和自旋哈密顿参数。
