摘要：
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)(2)Si-2. For 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 T-2 coefficient of the resistivity within it, shows that the field-tuned quantum criticality is intimately related to the phase formation.
