This paper describes the CaTi 1−x Mn x O 3 (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 CaTiO 3 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 CaMnO 3 sample exhibited antiferromagnetic ordering with T N near 113.26 K.
