Magnetization measurements on $Li2Pd3B$ superconductor

Magnetization in $dc$ magnetic fields and at different temperatures has been measured on the antiperovskite $Li2Pd3B$ with a cubic structure composed of distorted $Pd6B$ octahedrons. This material was recently found to exhibit superconductivity at $7–8K$⁠. The critical fields $Hc1(0)$ and $Hc2(0)$ are determined to be $135Oe$ and $4T$⁠, respectively. Critical current density, scaling of the pinning force within the Kramer model, and irreversibility field data are presented. Several superconductivity parameters were deduced: Coherence length $ξ=9.1nm$⁠, penetration depth $λ=194nm$⁠, and Ginzburg–Landau parameter $κ=21$⁠. The material resembles other boride superconductors from the investigated points of view.
