摘要

稀土超导体中反铁磁性的存在表现出各种新的物理现象。实验强调了反铁磁性超导体中的磁比热异常。本文以Ginzburg-Landau理论为基础，介绍了磁场对稀土超导体中反铁磁超导体相变到常态相变附近比热的影响。计算了反铁磁超导体相和正常态的磁比热。讨论了理论与实验之间的定性一致性。

Magnetic Specific Heat Near the Antiferromagnetic Superconductor Phase to Normal State Phase Transition in Rare-Earth Superconductors

The existence of antiferromagnetism in rare-earth superconductors exhibits varieties of new physical phenomena. Experiments have highlighted the magnetic specific heat anomalies in antiferromagnetic superconductor. Structured around a Ginzburg-Landau theory, this article presents the role of magnetic field on the specific heat near the antiferromagnetic superconductor phase to normal state phase transition in rare-earth superconductors. The magnetic specific heat is calculated both at the antiferromagnetic superconductor phase and normal state. The qualitative agreement between theory and experiment is discussed.
