Abstract

We report the observation of spin polarons in triangular lattice MoTe₂/WSe₂ moiré bilayers by reflective magnetic circular dichroism measurements. A spin polaron phase is identified at lattice filling factor between 0.8 and 1 and magnetic field between 2 and 4 T, separated from the fully spin polarized phase by a metamagnetic transition. The spin polaron is determined to be a spin-3/2 particle and its binding energy is commensurate with the kinetic hopping energy.
