Our low purity sample shows the superconducting transition at Tc = 104 degree C, in agreement with the previous result by quantum locking, based on the Meissner effect. Using the pure samples, resistance vs T will be measured soon.

For comparison, we show the Nobel Prize winning resistance vs T of LaBaCuO by Bednorz and Muller.
