The disorder can exert a dominant impact on correlated and quantum materials, resulting in unique behaviors that lack clear analogies in pristine conditions. In high entropy materials, the presence of multiple elements introduces a high atomic level disorder and gives rise to unique properties. In this paper, we have utilized the novel high entropy route to synthesize a new tetragonal high entropy spinel material (FeCoNiCuZn)MnO Despite high disorder, the magnetic investigations demonstrate a complex magnetic behavior with a ferrimagnetic-type transition at 150 K. An unusually high value of coercivity (1.1 T) and high magnetic frustration is observed here. Additionally, an element-sensitive synchrotron-based X-ray absorption spectroscopy has been utilized to discern its local geometric and electronic structure.

四方高熵尖晶石氧化物的复杂磁性和大矫顽力

这种紊乱可以对相关材料和量子材料产生显着影响，从而导致在原始条件下缺乏明确类比的独特行为。在高熵材料中，多种元素的存在引入了高原子级无序并产生了独特的性质。在本文中，我们利用新颖的高熵路线合成了一种新型四方高熵尖晶石材料（FeCoNiCuZn）MnO。尽管无序度很高，但磁性研究表明在 150 K 时具有亚铁磁型转变的复杂磁性行为。此处观察到矫顽力值（1.1 T）和高磁阻挫。此外，基于元素敏感的同步加速器的 X 射线吸收光谱已被用来辨别其局部几何和电子结构。
