Spin Fluctuations and Superconductivity in Mo3Sb7

Résumé

Temperature dependences of the magnetic susceptibility, specific heat, and electrical resistivity have been measured for the Mo3Sb7 compound in the 0.6 – 350 K range. This compound exhibits bulk superconductivity occurring at 2.25 K and follows the Kadowaki-Woods relation A/gamma2 = 1x10-5 µΩ cm (K.mol/mJ)2 a heavy-fermion system does. We show, from experimental evidence and theoretical argument, that Mo3Sb7 can be classified as a coexistent superconductor-spin fluctuation system. The McMillan equation including paramagnon effects was found to give an accurate estimation of the transition temperature.
