✦ Synopsis

The magnetization processes of the reentrant spin-glass Feo.65 Mno.35TiO 3 have been observed in magnetic fields with various sweep-rates by using a pulse magnet, a superconducting magnet and a water-cooled Bitter-type magnet. It has been found that there exists an essential difference between the magnetization processes in the sweep-rate regions 103 T/s (pulse magnet) and < 0.75 T/s (superconducting and Bitter-type magnets). The difference is considered to be due to the spin structure of a spin-glass state.
