The mixed state properties of superconducting YNi2B2C

YNi2B2C intermetallic superconductor has the fluctuation magnetoconductance showing the 3D scaling behavior. In the mixed state, due to this fluctuati on effect, the vortices form a solid phase at low temperature and make a li quid phase near T-c similar to high-T-c materials. Moreover, the Vortex sol id becomes a lattice at low fields and the vortex glass transition is found for high fields of H greater than or equal to 2 T while the liquid phase i s narrow.
