The comparable ionic-radius cation substitution provides a route to investigate the origin of the physical properties of ceramics on the local structure and electronic charge state background. In analogy to our previous work [19] of La₂CuMnO₆ (LCM) prepared via solid-state route, here we are reporting the effect of Zn substitution at the Cu site of LCM. The detailed structural analysis confirmed the Jahn-Teller (JT) distortion in LCM and Zn²⁺ substitution of LCM (i.e., LCZM) ceramics. Raman analysis further confirms the JT distortion in these oxides. O K-edge and Mn K-edge XANES spectra confirmed the mixed hybridization states for Mn. A frequency-dependent relaxor state was observed in the dielectric study of LCM and LCZM. The dielectric responses of these systems are prominently driven by electron-phonon coupling. Their magnetic studies showed positive-Curie temperature (T_C) and non-zero coercivity, indicating the ceramics' canted-antiferromagnetic nature.

可比较的离子半径阳离子取代提供了一种途径来研究局部结构和电子电荷态背景下陶瓷物理性质的起源。类似于我们之前通过固态途径制备的 La ₂ CuMnO _{6 (LCM) 的工作 [19]，我们在这里报告了 LCM 的 Cu 位点处 Zn 取代的影响。}详细的结构分析证实了 LCM 和 Zn ^{2+中的 Jahn-Teller (JT) 畸变}LCM（即LCZM）陶瓷的替代品。拉曼分析进一步证实了这些氧化物中的 JT 畸变。O K-edge 和 Mn K-edge XANES 光谱证实了 Mn 的混合杂交状态。在 LCM 和 LCZM 的介电研究中观察到频率依赖性弛豫态。这些系统的介电响应主要由电子-声子耦合驱动。他们的磁性研究显示正居里温度 ( T _C ) 和非零矫顽力，表明陶瓷的倾斜反铁磁性质。
