Link between magnetic field-induced quantum criticality and phase formation in (original) (raw)

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 UðRu 1Àx Rh x Þ 2 Si 2 : For x ¼ 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. r
