• De-stabilization of charge-order state through in-homogeneity in random ionic distribution in the particles of polycrystalline Eu$_{0.2}$La$_{0.3}$Sr$_{0.2}$Ca$_{0.3}$MnO$_3$ sample

In this study the perovskite manganite Eu$_{0.2}$La$_{0.3}$Sr$_{0.2}$Ca$_{0.3}$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-ordertransition) 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.
