Characterization of the Spin Reorientation Transition in HoFe<sub>1-x</sub>V<sub>x</sub>O<sub>3</sub>
POSTER
Abstract
We investigate the effect of V doping on the spin reorientation phenomenon in the holmium-based orthoferrite HoFe1-xVxO3. Spin reorientation arises from a reconfiguration of the magnetic structure that leads to a rotation of the net magnetic moment between crystal axes. Polycrystalline samples were synthesized via solid state reaction and characterized by vibrating sample magnetometry. It is established that the spin reorientation occurs below 50 K in HoFeO3, and our results show that the transition temperature increases with V substitution. A probable mechanism is that the V doping interferes with the Fe-Fe magnetic interactions and allows the Ho-Fe interactions to dominate at higher temperature, which leads to the spin reorientation.
