Abstract EN
We calculated the elastic properties of MgCNi3 at the superconducting transition (Tc) using various thermodynamic and acoustic data.
From the calculations, a step discontinuity of 8 ppm in the bulk modulus, 7 ppm in the Young’s modulus, and 3 ppm in the longitudinal sound velocity (vl) is expected at Tc.
The step discontinuities at the transition temperature indicated the importance of lattice changes to the superconducting mechanism of MgCNi3.
The Debye temperature was calculated to be 460 K.
The electron-phonon coupling constants calculated in the weak and strong coupling limits of the BCS theory and the van Hove scenario showed that MgCNi3 is a moderately strong coupled superconductor.
