Magnetic phase transition of the bond random mixed compound Fe(Br_xI_(1-x))2

摘要

The single crystal samples of Fe(Br_xI_(1-x))2 were investigated by the magnetization measurement. Among them, the x = 0.6, 0.8 and 0.9 samples were microscopically studied by the Mossbauer technique. As comparing the results of a magnetic behavior obtained for the x = 0.6, 0.8 and 0.9 samples, we discuss a spin glass-like behavior appeared in the bond random mixture. We propose an x–T magnetic phase diagram of Fe(Br_xI_(1-x))2.
