M. Elmassalami et al., STRUCTURAL, TRANSPORT, MAGNETIC AND SUPERCONDUCTING PROPERTIES OF THEPSEUDO-QUATERNARY INTERMETALLIC SYSTEM (Y1-XGDX)NI2B2C, Physica. C, Superconductivity, 235, 1994, pp. 2563-2564
The superconducting and the magnetic phase diagram (in x-T plane) of t
he pseudo-quaternary (Y1-xGdx)Ni2B2C series is obtained. Superconducti
vity is observed to be montonically degraded with Gd-concentration for
x < 0.25. For higher x two magnetic transitions are observed. The nat
ure of these transitions and their influence on the measured physical
properties will be discussed.
