Subleading terms of thermodynamic quantities around static spherical black holes

The thermodynamic quantities for the gases of massless particles with spin s = 1 / 2, 1, 3 / 2, 2 around static spherical black holes are investigated by using the brick-wall method. The appearance of the spin-dependent subleading terms is demonstrated and the terms are shown to contain not only the linear and quadratic terms of the spins but also a zero-power term of the spins.
