【摘要】 Tie magnetization behavior of a CuFeO2 single crystal grown by the floating zone technique is investigated with a pulsed high magnetic field.We observe a series of field-induced multi-step-like transitions with hysteresis,of which the critical magnetic fields are temperature-dependent and show anisotropy.By using a pulsed high magnetic Geld up to 75 T,the magnetization behavior shows that the critical transition magnetic Gelds of spinflip/flop shift to lower field regions with an increase in temperature.According to the magnetization curves,a complete magnetic phase diagram is depicted.
