520 _ _ |a The magnetic interactions between rare-earth and transition-metal moments are of significant interest in the study of permanent magnets [1-2]. In particular, the interplay between 4f and 3d magnetic moments leads to complex behaviors, giving rise to phenomena such as spin reorientation, exchange bias, multiferroicity, and spin switching [3]. Among rare-earth chromites, SmCrO₃ has been extensively investigated due to its complex magnetic phase diagram and potential multiferroic properties [4]. In rare-earth orthochromites, the Mn substitution at the Cr-site has shown versatile magnetic phenomena, and research on these materials has been revived in recent decades [5]. Many controversies over the microscopic spin configuration remain unsolved, presumably due to the complicated spin and orbit interactions. In the present study, SmCrO₃ was characterized by powder X-ray diffraction and Rietveld refinement, confirming an orthorhombic structure with the Pbnm space group. Magnetization measurements revealed a Néel transition at 192 K and a spin reorientation at 34 K. Mn-doping shifted these transitions to lower temperatures and induced a new low-temperature magnetic phase.In addition, we also investigated the effect of hydrostatic pressure in Mn-doped SmCrO₃. Applying pressures up to 1 GPa led to a slight increase in both the Néel and spin reorientation temperatures. Our results highlight Mn-doping and pressure as effective control parameters for tuning magnetic interactions in correlated materials.[1] M. Sagawa, et. al., J. Appl. Phys., 26, 785(1987).[2] R.
