Pressure-induced ferromagnetic phase in Ce2Fe16Mn1 compound

Abstract We have studied magnetization of the Ce 2 Fe 16 Mn 1 compound under high pressure up to 10 kbar and magnetic fields up to 5 T in the temperature range of 5–300 K. A metamagnetic transition from the helical antiferromagnetic structure ( T N =198 K ) into a ferromagnetic phase was observed at the critical field H CR =0.34 T at 5 K under ambient pressure. The field H CR increases with increasing temperature and decreases with pressure. At pressures above 2 kbar, the induced ferromagnetic phase was stabilized at low temperatures at zero magnetic field, in contrast to the behavior of Ce 2 Fe 17 . The results complete data on the strong correlation between the magnetic properties of the Ce 2 Fe 17− x Mn x (0⩽ x ⩽1.5) intermetallics and the lattice volume.
