Abstract

We report on a study of the magnetic properties of the intermetallic superconductor YNi₂B₂C in a wide range of magnetic fields (up to 8 T) and temperatures (4.4-16 K). The results yield the characteristic length scales and fields for this compound: λ (0) ≈ (3.5 ± 0.5) × 10^-5 cm, ξ(0) ≈ (10 ±2) × 10^-7 cm, H_c1 (0) ≈ 83 G and H_c2 (0)≈ 47600 G. We compare our results with those obtained by other groups and add new information on thermodynamic properties, in particular on the lower critical field, and on irreversible magnetic features such as the critical current, pinning force and magnetic relaxation. We conclude that YNi₂B₂C is a type-II superconductor with relatively weak pinning centers.
