英文摘要	In this work, we reported the magnetic and thermal properties of perovskite yfeo3 crystal grown by the floating zone method. yfeo3 crystal is a canted antiferromagnet with a weak ferromagnetic behavior. the magnetization varied nonlinearly from 0.204emu/g to 0.173emu/g at the temperature range of 2-300k. its neel temperature is around 644.5 k. the specific heat is about 0.56j/(g k) at room temperature and reaches the maximum value of 0.77j/(gk) at 644.5k where the antiferromagnetic-paramagnetic transition occurs. both the lattice and magnetic contributions to the heat capacity have been calculated. thermal diffusivity and the thermal conductivity are as large as 3.53 mm(2)/s and 11.27w/(m k) at 298 k, respectively. both of them show anomalies around the magnetic phase transition point. the average thermal expansion coefficients are -1.72 x 10(-6) k-1 and 2.28 x 10(-6) k-1 before and after neel temperature, respectively. the high neel temperature, high thermal conductivity and small expansion coefficient indicate that yfeo3 crystal is a promising candidate for laser-induced or optical device applications in broad temperature range and high power system.
