Quantum critical point and unusual phase diagram in the itinerant-electron metamagnet UCoAl

We present the temperature-pressure-magnetic-field phase diagram of the itinerant-electron metamagnet UCoAl determined from the ac susceptibility measurement. The quantum critical point (QCP) was found to be located at 2.9 + or - 0.2 GPa ( identical with P sub(QCP)) and 130 + or - 5 kOe. In addition...
