Abstract
The electrical resistivity, the magnetization, and the specific heat were measured. The residual resistivity ρ0 and the residual resistivity ratio ρR.T./ρ0 are 31 μΩ cm and 7.1, respectively. It was found that La3Co shows superconductivity below a transition temperature Tc of 4.4 K. The upper critical field Hc2 and lower critical field Hc1 at 0 K are estimated to be about 21 and 1 kOe, respectively, and using the relation of Hc1/Hc2≂ξ2/λ2, the ratio ξ/λ is estimated to be 0.2. The energy gap 2Δ and the Fermi energy are estimated to be 13×10−4 and 0.14 eV, respectively.This publication has 2 references indexed in Scilit:
