Abstract

We have conducted a thorough investigation into the magnetic properties of the compounds La_1/3Sr_1/3M_1/3CoO₃ (M=Ca, Ba). Despite sharing identical hole concentrations with La_1/3Sr_2/3CoO₃, the Ca-substituted variant manifests a reentrant cluster glass-like magnetic behavior, whereas the Ba-substituted counterpart displays ferrimagnetic characteristics. Based on the experimental results of dc magnetization and ac susceptibility, we confirmed that the observed disparate magnetic phenomena were predominantly attributed to the effects of A-site cation size disorder and the altered equilibrium among the competing interactions within the system.

La1/3Sr1/3M1/3CoO3 （M = Ca, Ba）的不同磁相变和磁特性

我们对化合物La1/3Sr1/3M1/3CoO3 （M=Ca, Ba）的磁性进行了深入的研究。尽管与La1/3Sr2/3CoO3具有相同的空穴浓度，但ca取代的变体表现出可重入簇玻璃般的磁性行为，而ba取代的变体则表现出铁磁性特征。基于直流磁化率和交流磁化率的实验结果，我们证实了所观察到的不同磁现象主要归因于a位阳离子尺寸紊乱和系统内竞争相互作用平衡的改变。
