摘要
采用标准固相法制备NiCr_(2)O_(4),并对其结构、磁性能和磁相变临界行为进行研究.研究结果表明:NiCr_(2)O_(4)具有尖晶石结构;当温度低于居里温度TC时,随着磁场强度增加,磁化强度趋于饱和;当温度高于TC,随着磁场强度增加,磁化强度线性增加,NiCr_(2)O_(4)呈顺磁特征;长程和短程铁磁相互作用共存于NiCr_(2)O_(4).
NiCr_(2)O_(4)was prepared by standard solid phase method,and its structure,magnetic properties and critical behavior of magnetic phase transition were studied.The results showed that NiCr_(2)O_(4)had spinel structure.When the temperature was lower than the Curie temperature T_(C),the magnetization tended to be saturated with the increase of magnetic field intensity.When the temperature was higher than T_(C),the magnetization increased linearly with the increase of magnetic field intensity,and NiCr_(2)O_(4)exhibited paramagnetic characteristics.Long range and short range ferromagnetic interactions coexisted in NiCr_(2)O_(4).
