| Research Abstract |
We built superconducting transition measurement system for small resistance material under high pressure. In fact, we measured superconducting transition at 50 GPa in BaTi2Sb2O. One of the square-planar iron oxides, Sr0.7Eu0.3FeO2, caused a valence fluctuation from Eu2+ to Eu3+ with increasing pressure and revealed a conduction plane to increasing carrier. But we cannot search a new superconductor.
