Abstract

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.

碲化镉弹性模块的低温磁场行为

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。

期刊介绍： Guided by an international editorial board, Low Temperature Physics (LTP) communicates the results of important experimental and theoretical studies conducted at low temperatures. LTP offers key work in such areas as superconductivity, magnetism, lattice dynamics, quantum liquids and crystals, cryocrystals, low-dimensional and disordered systems, electronic properties of normal metals and alloys, and critical phenomena. The journal publishes original articles on new experimental and theoretical results as well as review articles, brief communications, memoirs, and biographies. Low Temperature Physics, a translation of the copyrighted Journal FIZIKA NIZKIKH TEMPERATUR, is a monthly journal containing English reports of current research in the field of the low temperature physics. The translation began with the 1975 issues. One volume is published annually beginning with the January issues.
