We address a recent controversy concerning the magnetic state of holmium adatom adsorbed on platinum surface. Within a combination of the density-functional theory with the exact diagonalization of Anderson impurity model, the paramagnetic ground state |J = 8, Jz = ±8〉 is found. In an external magnetic field, this state is transformed to a spin-polarized state with Jz ≈ 6.7. We emphasize the role of 5d–4f interorbital exchange polarization in modification of the 4f shell energy spectrum.
