高温超导体中的铁弹涨落

Ferroelastic fluctuations in high-temperature superconductors

Fedor V. Prigara

摘要:

结果表明,磷属元素化物和铜氧化物超导体在超导转变温度下的比热跃变是由低于转变温度的铁弹涨落引起的。相应的晶格畸变的幅度估计。结果表明,在低温超导体中,铁弹涨落对比热跃变也有贡献。

英文摘要:

It is shown that the specific heat jump at the superconducting transition temperature in pnictide and cuprate superconductors is produced by ferroelastic fluctuations just below the transition temperature. The amplitude of the corresponding lattice distortion is estimated. It is shown that a contribution from ferroelastic fluctuations to the specific heat jump is also present in low-temperature superconductors.
