Itinerant metamagnetic transition in the ferromagnet LuCo3 induced by high field: instability of the 3d-electron subsystem
Original language description
LuCo3 is an itinerant ferromagnet whose magnetic properties strongly depend on the position of the 3d electronic states relative to the Fermi level. We report on the magnetization of LuCo3 single crystal in pulsed magnetic fields up to 58 T. We find a field-induced phase transition at 50 T from a low-spin to a high-spin state. The transition shows a pronounced anisotropy of the magnetization jump and hysteresis. Series of ab initio calculations showed that the transition is due to a significant change in the occupancies of the Co 3d electronic states. At the same time, some features in the majority spin density of the Co 3d states are slightly modified and pass through the Fermi level when the spin state is changed, which leads to the instability of the 3d-electron subsystem. The applied magnetic field causes a significant redistribution in the majority and minority spin states in the Co 3d subsystem, which results in the sharp change in the magnetization.
