为了实现碳中性，基于磁热效应的固态相变制冷技术被认为是最有潜力替代传统制冷技术的制冷技术之一。在现阶段，固定和相对狭窄的工作温度窗口仍然是未来制冷应用的主要劣势。因此，这项工作的目的是表明，在Ni-Mn-In-Co MCE材料中，工作温度可以通过静水压力或双向应力来动态调节。结果表明，Ni21Mn18在6Co3中的工作温度范围在310K到328K之间可调。与静水压力不同，双轴压缩或拉伸应力可以实现对马氏体相变温度的双向控制，进一步拓宽了工作温度范围。−1.5~1.5%的双轴应变可以使Ni21Mn18In 6Co3合金的工作温度在292~344K范围内调谐。并详细揭示了利用物理压力动态控制和提高Ni-Mn-In-Co合金工作温度范围的物理机理。此外，静水压力和双向应力都没有降低居里温度(TC)，并改善了奥氏体相和NM马氏体相之间的磁化强度差(ΔM)。这进一步证明，施加物理压力可以是一种同时提高工作温度和磁性能的有效策略。支持这项研究结果的数据可在文章中找到。
In order to achieve carbon neutrality, solid-state phase-change refrigeration technology based on magnetocaloric effects (MCE) is considered one of the most potential alternatives to traditional refrigeration technology. At this stage, the fixed and relatively narrow operating temperature window still remains a major disadvantage for future refrigeration applications. Hence, this work aims to show that working temperature in Ni-Mn-In-Co MCE materials can be dynamically tuned by hydrostatic pressure or biaxial stress. Our results show that Ni 21 Mn 18 In 6 Co 3 presents adjustable operating temperature range (from 310 K to 328 K) under pressure (0–3 GPa). Unlike hydrostatic pressure, biaxial stress with compression or tension can achieve bidirectional control of martensitic transformation temperature, further widening the operating temperature range. The biaxial strain from − 1.5–1.5 % can tune the operating temperature range from 292 K to 344 K in Ni 21 Mn 18 In 6 Co 3 alloys. Also, the physical mechanism of dynamic control and increase of working temperature range in Ni-Mn-In-Co using physical pressures is revealed detailly. Moreover, the results show that both hydrostatic pressure and biaxial stress do not decrease the curie temperature ( T C ), and improve the magnetization difference (Δ M ) between austenite and NM martensite phases. It further proves that applying physical pressures can be an effective strategy with simultaneous enhancement of working temperatures and magnetic properties. The data that supports the findings of this study are available within the article.
