Magnetization of a Dy2Fe14Si3single crystal in high magnetic fields

Abstract

The magnetization of a Dy2Fe14Si3 single crystal was measured at 4.2 K in pulsed fields up to 52 T along the principal axes. The compound is a ferrimagnet with TC = 500 K, has a spontaneous magnetic moment of 9 μB(at 4.2 K) and exhibits a very large magnetic anisotropy, ⟨100⟩ being the easy axis. In fields applied along the ⟨100⟩ and ⟨120⟩ axes, field-induced phase transitions are observed at 33 T and at 39 T, respectively. The c-axis magnetization curve crosses the easy-axis curve at 23 T. At higher fields, for all directions, the magnetization continues to increase due to further bending of the sublattice moments.
