Material Specification for ; [Y-Ni-B-C]
Process: Melt Processed
Notes: "Yttrium 99.9% purity, supplied by Rare Earth Products Inc., nickel (99.99% purity), boron (99.9% purity) and carbon (99.999% purity) supplied by Koch Light Labs. were used for direct synthesis of the elements. Three samples of the phase were prepared in form of pellets from stoichiometric amounts of the constituents and melted at a temperature well above the melting point in a semilevitation high frequency induction furnace on a water cooled tantalum hearth under an atmosphere of pure and dry argon. The pellets were remelted three times to ensure complete homogeneity. ... Metallographic analyses... showed that the obtained compound was single phase with little grain separation ( < 1%)."

c = 1.4 K. The annealing procedure had no effect on the transition onset and width. ... Using the Beam model it is possible to (evaluate) the critical current density from the irreversible magnetization. ... We defined the first critical field at a fixed temperature as the point where the M-H linear behaviour is lost. To (evaluate) H
we observed the derivative of the magnetization with respect to the applied magnetic field versus the applied field, and we identified the field where the derivative is no longer constant and equal to -1. ...the upper critical field... was identified as the... field for the temperature at which no appreciable diamagnetic contribution could be detected."
