要旨:
The magnetization and resistivity studies in magnetic fields up to 45 T were used to establish magnetic field versus temperature phase diagram and quantum criticality in U(Ru1-xRhx)2Si2U(Ru1-xRhx)2Si2. For x=4%x=4%, the hidden order is completely destroyed, stabilizing a single field-induced phase II. A correlation between the field dependence of this phase and that of the quantum critical point, combined with the suppression of the T2T2 coefficient of the resistivity within it, shows that the field-tuned quantum criticality is intimately related to the phase formation.
