Popis:	Normal-state electrical resistivity of an A-15 compound V3Sn with a resistivity ratio of 5.78 and a T c of 4.10 K is reported as a function of temperature. The low temperature results are fit well with the T 3 law of the Wilson theory. The high temperature results, on the other hand, show a deviation from the linear T law. This deviation cannot be explained by taking into account the actual electronic density of states and the anharmonicity of phonon mode, which are introduced to improve the Wilson theory. The phenomenological expression based on the saturation model is well fitted to the high temperature results.
