Magnetic-field-tuned quantum criticality of the heavy-fermion system YbPtBi
Magnetic-field-tuned quantum criticality of the heavy-fermion system YbPtBi
In this paper, we present systematic measurements of the temperature and magnetic field dependencies of the thermodynamic and transport properties of the Yb-based heavy fermion YbPtBi for temperatures down to 0.02 K with magnetic fields up to 140 kOe to address the possible existence of a field-tuned quantum critical point. …
