摘要：

The temperature dependence of the specific heat and electrical resistivity has been measured for Pr3Tl. Pr3Tl is an induced moment ferromagnet for which Γ/Δ is just above the threshold value for magnetic ordering where Γ is the inter-ionic exchange and Δ is the crystalline electric field splitting of the Pr3+ ions angular momentum multiplet. Above Tc, the resistivity is substantially larger than would be expected using a single ion model. This additional contribution is attributable to the scattering from the low lying collective magnetic excitations. The temperature dependence of the resistivity and specific heat is discussed.
