Abstract:
We investigate the detailed analysis of the magnetic properties in a series of Pr 1– x Sm x FeO 3 single crystals from x = 0 to 1 with an interval of 0.1. Doping controlled spin reorientation transition temperature T SR Γ 4 ( G x , A y , F z ) to Γ 2 ( F x , C y , G z ) covers a wide temperature range including room temperature. A ‘butterfly’-shape type-I spin switching with 180° magnetization reversal occurs below and above the magnetization compensation points in x = 0.4 to 0.8 compounds. Interestingly, in Pr 0.6 Sm 0.4 FeO 3 single crystal, we find an inadequate spin reorientation transition accompanied by uncompleted type-I spin switching in the temperature region from 138 to 174 K. Furthermore, a type-II spin switching appears at 23 K, as evidenced from the magnetization curve in field-cooled-cooling (FCC) mode initially bifurcate from zero-field-cooled (ZFC) magnetization curve at 40 K and finally drops back to coincide the ZFC magnetization value at 23 K. Our current research reveals a strong and complex competition between Pr 3+ –Fe 3+ and Sm 3+ –Fe 3+ exchange interactions and more importantly renders a window to design spintronic device materials for future potential applications.
