We report the synthesis procedure and the chemical-physical characterization of the YNi2B2C superconductor. From magnetic measurements we show that this material is a type-II superconductor. We evaluate the penetration depth, the coherence length and, thus, the Ginzburg-Landau parameter. Despite the low value of κ(12), a very large region of reversibility in the H-T plane is observed.

Abstract
We report the synthesis procedure and the chemical-physical characterization of the YNi2B2C superconductor. From magnetic measurements we show that this material is a type-II superconductor. We evaluate the penetration depth, the coherence length and, thus, the Ginzburg-Landau parameter. Despite the low value of κ(12), a very large region of reversibility in the H-T plane is observed.
