Abstract

The temperature dependence of the resistivity, ρ(T) and magnetoresistivity (T ≥ 1.5 K, B ≤ 8 T) of polycrystalline U₂Pt₂Sn are reported. ρ(T) shows maxima at 12 K and 45 K and a minimum at 19 K. A minimum is observed in dρ(T)/dT at the Néel temperature of 15 K. The magnetoresistance at low temperatures is negative and below T_N it displays a step-like decrease in an applied field of about 2 T indicating the presence of a phase transition.
