This paper describes the CaTi_1−xMn_xO₃ (x = 0.0, 0.4, 0.6, 0.8 and 1.0) system synthesis using the solid-state reaction (SSR) method. The structural, morphological, and magnetic properties of Mn ion were evaluated in the CaTiO₃ system through X-ray diffraction patterns (XRD), scanning electron microscopy + electron-dispersive spectroscopy (SEM + EDS), and vibrating sample magnetometry. Rietveld analysis of the XRDs at room temperature evidenced that the samples crystallized in the Pnma (62) space group. Likewise, the XRDs showed that lattice parameters decreased when increasing Mn content. The SEM + EDS results exhibited typical features of samples obtained by SSR at high temperatures. The zero-field cooling and field cooling curves of magnetization in temperatures ranging from 50 to 300 K showed paramagnetic behavior in the applied field for each Mn-doped sample with a possible weak ferromagnetic-like ordering. Conversely, the CaMnO₃ sample exhibited antiferromagnetic ordering with T_N near 113.26 K.

本文描述了 使用固态反应 (SSR) 方法的 CaTi _{1− x} Mn _x O ₃ ( x = 0.0、0.4、0.6、0.8和 1.0) 系统合成。通过X射线衍射图（XRD）、扫描电子显微镜+电子色散光谱（SEM + EDS）和振动样品磁强计评估了CaTiO ₃体系中Mn离子的结构、形态和磁性。室温下 XRD 的 Rietveld 分析证明样品在Pnma中结晶(62) 空间群。同样，XRD 表明随着 Mn 含量的增加，晶格参数降低。SEM + EDS 结果展示了 SSR 在高温下获得的样品的典型特征。在 50 到 300 K 的温度范围内，磁化的零场冷却和场冷却曲线在每个掺杂 Mn 的样品的外加场中显示出顺磁行为，可能具有弱铁磁状排序。相反，CaMnO ₃样品表现出反铁磁有序性，T _N接近 113.26 K。
