Abstract

In this investigation, it is used a phenomenological model to predict the thermomagnetic properties through making simulation of experimental isofield thermo-magnetization curve for Sc doped Th₂NiC₂ superconductors. Consequently, the magnetocaloric effect (MCE) of Sc doped Th₂NiC₂ superconductors, in the vicinity of superconducting phase transition, is simulated, calculating MCE parameters. The results show that MCE of Sc doped Th₂NiC₂ superconductors are inverse type in temperature range of superconducting phase transition. The behavior of MCE in Th_1.9Sc_0.1NiC₂ and Th_1.8Sc_0.2NiC₂ samples recommends that they can fruitfully be utilized as very low-temperature magnetic refrigerants between 7 and 11 K especially in radiation detectors for outer space research.

Sc掺杂Th2NiC2超导体的磁热效应研究

摘要

本研究采用唯象模型，通过模拟Sc掺杂Th ₂ NiC ₂超导体的实验等场热磁化曲线来预测热磁特性。_{因此，模拟了Sc掺杂的Th 2} NiC ₂超导体在超导相变附近的磁热效应（MCE），计算了MCE参数。结果表明，Sc掺杂的Th ₂ NiC ₂超导体的MCE在超导相变温度范围内呈反型。MCE 在 Th _1.9 Sc _0.1 NiC ₂和 Th _1.8 Sc中的行为_0.2 NiC ₂样品建议它们可以有效地用作 7 到 11 K 之间的极低温磁性制冷剂，尤其是用于外层空间研究的辐射探测器。
