Magnon dressing by orbital excitations in ferromagnetic planes of K2CuF4 and LaMnO3
We show that even when spins and orbitals disentangle in the ground state, spin excitations are renormalized by the local tuning of e _g orbitals in ferromagnetic planes of K _2 CuF _4 and LaMnO _3 . As a result, dressed spin excitations (magnons) obtained within the electronic model propagate as qu...
