WebJul 4, 2024 · Spin reorientation is a magnetic phase transition in which rotation of the magnetization vector with respect to the crystallographic axes occurs upon a change in the temperature or magnetic field. For example, SmFeO 3 shows a magnetization rotation from the c axis above 480 K to the a axis below 450 K, known as the Γ 4 → Γ 2 transition. WebJul 15, 2024 · SmFe 1-x Cr x O 3 ( x = 0–0.3) were synthesized using the sol-gel method. Suitable proportions of samarium nitrate [Sm (NO3) 3 6H 2 O], ferric nitrate [Fe (NO 3) 3 9H 2 O] and chromium nitrate [Cr (NO 3) 3 4H 2 O] were used as the starting materials. The details of sample preparation processes can be found in Refs. [ 16, 17 ].
