Single-particle excitation spectrum of the Hubbard model in infinite-dimension is calculated under finite magnetic field by using the quantum Monte Carlo and the maximum entropy methods. It is found that (1) the filled part of the up-spin band expands and the empty part shrinks, while the down-spin
