Abstract

Terbium doped Ni-Cd mixed ferrite samples with general formula Ni0.9Cd0.1TbxFe2-xO4 (x = 0, 0.02, 0.06 and 0.1) were prepared through sol-gel technique. The effect of terbium doping on the properties of Ni-Cd ferrite has been investigated using different characterization techniques like X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Wavelength Dispersive X-Ray Fluorescence Spectrometer (WD-XRF), Transmission Electron Microscope (TEM) and Vibrating Sample Magnetometer (VSM). XRD analysis confirmed the formation of single phase spinel structure in all the samples. Tb3+ doping has resulted in increased saturation magnetization and enhanced resistivity of Ni-Cd mixed ferrite.Terbium doped Ni-Cd mixed ferrite samples with general formula Ni0.9Cd0.1TbxFe2-xO4 (x = 0, 0.02, 0.06 and 0.1) were prepared through sol-gel technique. The effect of terbium doping on the properties of Ni-Cd ferrite has been investigated using different characterization techniques like X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Wavelength Dispersive X-Ray Fluorescence Spectrometer (WD-XRF), Transmission Electron Microscope (TEM) and Vibrating Sample Magnetometer (VSM). XRD analysis confirmed the formation of single phase spinel structure in all the samples. Tb3+ doping has resulted in increased saturation magnetization and enhanced resistivity of Ni-Cd mixed ferrite.

Tb3+掺杂镍镉混合铁氧体的结构变化、磁性能和介电性能

采用溶胶-凝胶法制备了通式为Ni0.9Cd0.1TbxFe2-xO4 (x = 0、0.02、0.06、0.1)的掺铽镍镉混合铁氧体样品。采用x射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、波长色散x射线荧光光谱仪(wb - xrf)、透射电镜(TEM)和振动样品磁强计(VSM)等表征技术研究了铽掺杂对Ni-Cd铁氧体性能的影响。XRD分析证实所有样品均形成了单相尖晶石结构。Tb3+的掺杂提高了镍镉混合铁氧体的饱和磁化强度和电阻率。采用溶胶-凝胶法制备了通式为Ni0.9Cd0.1TbxFe2-xO4 (x = 0、0.02、0.06、0.1)的掺铽镍镉混合铁氧体样品。采用x射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、波长色散x射线荧光光谱仪(wb - xrf)、透射电镜(TEM)和振动样品磁强计(VSM)等表征技术研究了铽掺杂对Ni-Cd铁氧体性能的影响。XRD分析证实所有样品均形成了单相尖晶石结构。Tb3+的掺杂提高了镍镉混合铁氧体的饱和磁化强度和电阻率。
