Abstract
Here, the authors report temperature-dependent spin Hall magnetoresistance (SMR) of Pt on the complex antiferromagnet DyFeO${}_{3}$. The symmetry of the SMR as a function of in-plane magnetic field angle shows a 3D rotation of the Fe${}^{3+}$ N\'eel vector $G$, while the paramagnetic Dy${}^{3+}$ affects its magnitude. The SMR monitors the phase transition of Fe${}^{3+}$ spins at and below the Morin temperature of 50 K. Below 23 K, additional features emerge that persist below 4 K, the ordering temperature of the Dy${}^{3+}$ magnetic sublattice.
