Abstract
The equilibrium magnetization M of single crystal YNi2B2C superconductor ha s been studied with magnetic field H parallel to c axis. The material is cl ean, with low electrical resistivity and weak magnetic hysteresis (for PI = 10 kG, the critical current density is less th;ln 10(-6) of the depairing current density). The magnetization M(H) deviates from conventional London predictions, but is well described by recent nonlocal London theory, with w ell-behaved superconductive parameters. The temperature dependence of the L ondon penetration depth lambda(T) and other parameters are deduced. [S0163- 1829(99)50810-2].
