TEMPERATUREhyphen;INDUCED SPIN REORIENTATION IN RARE EARTH ORTHOFERRITESmdash;HYSTERESIS LOOP STUDIES

摘要

The spontaneous reorientation of the weak ferromagnetic moment (``temperaturehyphen;induced spin flop'') in the rare earth orthoferrites is found to take place over a wellhyphen;defined temperature range. In TmFeO3, this range is 12deg;K wide and centered at 88deg;K. Susceptibility peaks have been observed at the ends of this temperature interval where the magnetic easy axis just begins to rotate away from theaorcaxis.
