| Research Abstract |
Magnetic quantum criticality is one of the most intriguing phenomena in the condensed matter physics. In order to investigate its novel properties, we determined magnetic temperature-pressure-magnetic field phase diagram and the quantum critical end point (QCEP) of itinerant metamagnetic material UCoAl. We found unusual behavior in the electrical resistivity in the vicinity of the QCEP, which cannot be explained in terms of the non-Fermi liquid regime based on the SCR theory.
