Abstract

We performed DC-magnetization and neutron scattering experiments under pressure P for a pressure-induced superconductor UGe2. We found that the magnetic moment is enhanced at a characteristic temperature T* in the ferromagnetic state, where T* is smaller than a Curie temperature TC. This enhancement becomes remarkable in the vicinity of P*C = 1.20 GPa, where T* becomes 0 K and the superconducting transition temperature TSC shows a maximum. The characteristic temperature T*, which decreases with increasing pressure, also depends on the magnetic field.
