Magnetic-to-nonmagnetic transition in the ferromagnetic heavy fermion compound at high pressures

A zero-temperature magnetic-to-nonmagnetic transition has been investigated in the heavy-fermion ferromagnet (Formula presented) from electrical-resistance measurements at pressures up to 15 GPa and temperatures down to 60 mK. We found that the magnetic-to-nonmagnetic phase boundary exists at around (Formula presented). The resistivity shows the quadratic temperature variation expected for the conventional Fermi liquid at low temperatures near (Formula presented) In the present pressure range, neither the metamagnetic nor the superconducting transition was observed at least down to 60 mK.
