摘      要：The interplay of electron correlations and topological phases gives rise to various exotic phenomena including fractionalization,excitonic instability and axionic *** discovered transition-metal pentatellurides can reach the ultra-quantum limit in low magnetic fields and serve as good candidates for achieving such a ***,we report evidence of density wave and metal-insulator transition in HfTe5induced by intense magnetic *** the non-linear transport technique,we detect a distinct non-linear conduction behavior in the longitudinal resistivity within the a-c plane,corresponding to the formation of a density wave induced by magnetic *** high fields,the onset of non-linear conduction in the Hall resistivity indicates an impurity-pinned magnetic freeze-out as the possible origin of the insulating *** frozen electrons can be gradually reactivated into mobile states above a threshold of electric *** experimental evidence calls for further investigation into the underlying mechanism of the bulk quantum Hall effect and field-induced phase transitions in pentatellurides.
