Research Abstract |
We investigated the pressure-induced valence change and metamagnetic behavior in the vicinity of a magnetic quantum phase transition tuned by pressure and/or magnetic field. We have revealed a characteristic pressure-induced Yb valence crossover within the temperature-pressure phase diagram of YbNi3Ga9 in the vicinity of the magnetic quantum phase transition. Moreover, a first-order metamagnetic transition is found below the critical pressure.
