Abstract Scope Previously, we found an upturn of the electrical resistivity of UZr2 with a minimum at around 15 K and positive magnetoresistance [1]. To understand the nature of this unusual behavior and the source of the additional scattering mechanism of the conduction electrons at low temperatures, we have performed detailed low-temperature transport studies (down to 0.1 K) of this material under applied magnetic fields (up to 9 T). We find that the temperature dependence of magnetoresistance is independent of magnetic fields as high as 9 T. This is in agreement with the orbital Kondo resonance effect that should be weakly influenced by the magnetic field. It is also established that a two-level system determines the low-temperature thermal properties of materials with the disorder and a similar anomalous term is observed in the low temperature dependence of heat capacity of this material.[1] X.
