摘要

Columbite Zn0.8Co0.2Nb2O6 crystals were grown by optical floating zone methods.The x-ray diffraction (XRD) was used to check the structure information of the grown Zn0.8Co0.2Nb2O6 crystal.The room temperature and temperaturedependent Raman spectra were tested to investigate the optical phonon behaviors of columbite Zn0.8Co0.2Nb2O6,which exhibited a temperature stable property.The magnetics properties of Zn0.8Co0.2Nb2O6,measured by a physical property measurement system (PPMS),were also presented in this work.
