In this study the perovskite manganite \(\hbox {Eu}_{0.2}\hbox {La}_{0.3}\hbox {Sr}_{0.2}\hbox {Ca}_{0.3}\hbox {MnO}_{3}\) batch integrated sample is studied, with special modification done to introduce localized structural strain without micro-level (grains) modification. This consequence successfully generates opposite nature of high orthorhombic strain along b-axis in these samples, although the general structure is same for both with Pnma space group. The sharp magnetic transitions (both Curie temperature and charge-order transition) are reported to be mixed in presence of random ionic distribution in its structure. The diffused insulator-metal behaviour, de-stabilization of magnetic state and phase transitions associated with inherent anisotropic strain is discussed and is explained based on chemical disorder-induced structural strain in the present system.

在本研究中，钙钛矿锰矿\（\ hbox {Eu} _ {0.2} \ hbox {La} _ {0.3} \ hbox {Sr} _ {0.2} \ hbox {Ca} _ {0.3} \ hbox {MnO} _研究了{3} \）批处理的集成样本，并进行了特殊修改，以引入局部结构应变，而没有进行微级（晶粒）修改。这些结果成功地在这些样品中产生了沿b轴的正交斜应变的相反性质，尽管Pnma的总体结构相同空间群。据报道，尖锐的磁跃迁（居里温度和电荷阶跃跃迁）在其结构中存在随机的离子分布时混合在一起。讨论了绝缘子-金属的扩散行为，磁态的不稳定以及与固有各向异性应变相关的相变，并在本系统中基于化学无序引起的结构应变进行了解释。
