Key Points

This research investigates how Sm doping affects the spin dynamics in NdFeO3, focusing on temperature shifts in spin behavior.
Substituted iron oxide structures with varying Sm concentrations
Examined effects of negative-field-cooling bias on spin temperatures
Measured spin-switching temperatures under specific magnetic field conditions
Sm substitution raises the spin-reorientation temperature of the Fe-sublattice.
A negative-field-cooling bias results in a spin-switching temperature increase of approximately 158 K.
Specific temperature ranges for spin switching were identified as 175–333 K at H = 20 Oe.

Abstract

In Nd 1− x Sm x FeO 3 , Sm substitution shifts the Fe-sublattice spin-reorientation window to a higher temperature; in Nd 0.5 Sm 0.5 FeO 3 , a weak −20 Oe negative-field-cooling bias moves the spin-switching temperature by ∼158 K (175–333 K) at H = 20 Oe.
