Superconducting materials of nominal composition Bil.7Pb0.3Sr2Ca2CusO r were prepared by the cast annealing method. Electromagnetic measurements and X-ray powder diffraction patterns from the samples show that the major phase of the oxide superconductor is the superconducting phase at 110 K, with ze
First-harmonic x, and third-harmonic x3 a.c. susceptibility measurements have been carried out on a Hg0.66Pb,,34Ba2Ca2Cu 2 0 8+s sample. The frequency dependence of the onset temperature of x3 can be described well by T,,( fl = C(27~fl'I((~-')~) + Tg. Extrapolating to f=O, we derived the vortex glas
