摘要: By using the brick-wall model we calculate the free energy and the entropy including the superradiant effect mode of the scalar field in Demianski-Newman black hole. When the radial cut-off factor \barε and the angular cut-off factor δ satisfy a proper relation, the entropy can be written as S=AH/4.
