The perovskite-type vanadium oxide, ErVO3, with Jahn-Teller active t2g electrons at the V site, is a prototypical correlated electron system with orbital degrees of freedom [1-3]. It features an intimate interplay between spin, orbital, and lattice interactions leading to several magnetic transitions. We have performed muSR on the perovskite vanadate ErVO3. Magnetic susceptibility, specific heat, and neutron diffraction measurements on single crystals reveal orbital ordering and orbital-flipping transitions, as well as spin ordering/spin reorientation transitions. Our muSR survey picks up these magnetic transitions and spin freezing of about 20% of the sample volume below 3 K. [1] P. Telang et al, Journal of Crystal Growth 507, 406-412 (2019) [2] P.
