Temperature hysteresis of the elastic modulus and low-temperature local phase transformations of the order-disorder type in the superconductor YBa2Cu3Oxстатья
Аннотация:The temperature hysteresis of the Young modulus is observed in YBa2Cu3Ox compounds with 6.24⩽x⩽6.9. The effect is interpreted in terms of local order-disorder phase transitions of the first kind in the temperature range 4.2–300 K.
