摘要

固态磁性材料在文章编号 2409270 中，张凤岐、马凤杰、任扬及其合作者在掺杂 Ni/Pd/Pt 的 (Mn,Fe)2(P,Si)基材料中实现了优异的 GMCE 性能，这几乎超过了迄今为止报道的所有其他具有 ΔThys (<10 K) 的材料。其机理可从 3d-4d-5d 元素之间的磁交换相互作用和轨道杂化之间的竞争中得到理解。这些研究为进一步优化该材料家族的 GMCE 提供了一种通过 d 块掺杂的通用策略。

Achieving Tunable High-Performance Giant Magnetocaloric Effect in Hexagonal Mn-Fe-P-Si Materials through Different D-Block Doping (Adv. Funct. Mater. 45/2024)

Solid-State Magnetocaloric Materials

In article number 2409270, Fengqi Zhang, Fengjie Ma, Yang Ren, and co-workers achieve excellent GMCE performance in Ni/Pd/Pt doped (Mn,Fe)₂(P,Si)-based materials, which surpasses almost all others with ΔT_hys (<10 K) reported until now. The mechanism is understood from the competition between magnetic exchange interactions and orbital hybridization among 3d-4d-5d elements. The studies provide a general strategy through d-block doping to further optimize the GMCE of this materials family.
