Spin polaron hopping in Li-doped CuO. Diagram describing the interplay of spin and polaron hopping in CuO after Li doping (orange = Li). As the spin polaron hops through the lattice, its interaction with Li will result in a lower magnetic barrier \(E_{\mathrm a}^{{\mathrm {spin}}}\) due to broken magnetic couplings between Cu ions and nonmagnetic Li ions (Espin = 0)
