✦ Synopsis


Magnetic phase diagrams of CeS and CeSe have been studied by neutron scattering, magnetoresistance and magnetization experiments. Along the easy axis [110] the magnetization curve of CeS at 4.2 K shows two steps at 5.6 and 9 T. In CeSe at 1.7 K a first-order phase transition occurs at 5.7 T in fields along [110] and [111].

The mechanism of how the magnetic field controls the critical end point of the first-order valence transition is clarified, which is essentially ascribed to charge degrees of freedom. It is shown that the quantum critical point is induced by applying the magnetic field, which explains a peculiar mag
