Abstract
The existence of a superconducting phase transition well above 77 K in the multiphase compound, Y1.2Ba0.8Cu04 as reported recently1 was confirmed by our study. The observed superconducting onset temperature (~ 110 K) and the temperature at which the zero-resistance state is achieved (87K) in our samples, to our knowledge, are the highest ever reported among the stable superconducting compounds. The transition width (~2 K) is also narrower compared to that reported by Wu et al.
