摘要

提出了碲化镉 2 外磁场中声速（及相关弹性模块）的低温行为理论。该理论基于双重模型。该模型考虑了 U 离子的 5f2 电子：巡回电子（其中部分电子形成对，负责超导性）和局部电子。该理论解释了在 UTe2 中低温下观察到的类似元磁性的磁场跃迁。

Low-temperature magnetic field behavior of elastic modules in UTe2

The theory for the low-temperature behavior of sound velocities (and related elastic modules) in the external magnetic field in UTe2 is proposed. The theory is based on the dual model. The model takes into account 5f2 electrons of U ions: both itinerant electrons (part of which form pairs, responsible for the superconductivity) and localized ones. The theory explains the metamagnetic-like jumps in the magnetic field observed at low temperature in UTe2.
