Abstract
Two simple effective models for the low-temperature (however higher than the temperature of the transition to the superconducting phase) behavior of magnetic and magnetocaloric characteristics in the external magnetic field in UTe2 are proposed. The models are based on the dual nature of 5f electrons and take into account both itinerant electrons and localized electrons of U ions. Several magnetic characteristics including the magnetocaloric ones have been calculated for those scenarios. It is expected that by observing the features of the characteristics of the magnetocaloric effect in UTe2 and comparing them with the ones, predicted by the theory, one can choose the model, that can better describe the specific magnetic properties of UTe2 at low temperatures in the normal phase.
针对碲化镉(UTe2)在外部磁场中的低温（但高于向超导相转变的温度）磁性和磁致特性行为，提出了两个简单有效的模型。这些模型基于 5f 电子的双重性质，并考虑到了 U 离子的巡回电子和局域电子。针对这些方案计算了包括磁致性在内的若干磁特性。通过观察碲化镉的磁致效应特征并将其与理论预测的特征进行比较，我们可以选择能更好地描述碲化镉在低温下正常相的特定磁特性的模型。
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.
