摘要:

We made the superconductor of Bi2Sr2CaCu2Oγby the solid state reaction. According to the results of measurement by infrared spectrophotometer with the varying of wave number from 4000 to 400 cm−1. We discovered three infrared absorption peaks at room temperature, i.e., peak A1at 500–550 cm−1, peak A2at 800–840 cm−1and peak A3at 1370–1420 cm−1. We find that peak A1is due to impure phase, peak A2is related with the crystal structure and peak A3is caused by the vibration of the atom layers of calcium.
