Abstract

The magnetization measurement of an exchange-enhanced Pauli paramagnet YCo2 has been made at 10 K in pulsed ultra-high magnetic fields up to 94 T to examine the existence of itinerant electron metamagnetism. The field induced phase transition from a paramagnetic to a ferromagnetic state has been observed for the first time at about 70 T, indicating a clear evidence for the existence of metamagnetism.
