Pressure-induced ferromagnetism with strong Ising-type anisotropy in YbCuSi

Tateiwa, Naoyuki ; Matsuda, Tatsuma*; Haga, Yoshinori ; Fisk, Z.

We report dc magnetic measurements on YbCuSi at pressures above 10 GPa using a miniature ceramic anvil cell. YbCuSi shows a pressure-induced transition from the non-magnetic to a magnetic phase at 8 GPa. We find a spontaneous dc magnetization in the pressure-induced phase above 9.4 GPa. The pressure dependence of the ferromagnetic transition temperature $T_{rm C}$ and the spontaneous magnetic moment ${mu}_0$ at 2.0 K have been determined. The pressure-induced phase has strong Ising-type uniaxial anisotropy.
