THE STRUCTURAL PHASE TRANSITION NEAR 210 K OF Bi-BASED SUPERCONDUCTORS

THE STRUCTURAL PHASE TRANSITION NEAR 210 K OF Bi-BASED SUPERCONDUCTORS

Recently, systematic investigations on Bi-based superconductors were carried out by means of ultrasonic measurements, thermal analysis, specific heat experiments and X-ray diffraction measurements. It was found for the first time that a possible structural phase transition occurs near 210 K in these...

Zusammenfassung:Recently, systematic investigations on Bi-based superconductors were carried out by means of ultrasonic measurements, thermal analysis, specific heat experiments and X-ray diffraction measurements. It was found for the first time that a possible structural phase transition occurs near 210 K in these systems. All the samples used were of single phase and
