ENHANCEMENT OF THE SUPERCONDUCTING TRANSITION-TEMPERATURE OF TLSR2CACU2O7 BY YTTRIUM AND VANADIUM SUBSTITUTIONS
Superconductivity at 105 K has recently been observed in a family of compounds (Tl1-xMx)Sr2(Ca1-yYy)Cu2O7-δ (M = Ti, Zr, Hf, V, Nb, and Ta). An interesting feature is the enhancement of Tc in the parent TlSr2CaCu2O7 compound via substitution of high-valent 3d transition metals; this is in contrast t...
