Abstract
By using the Teukolsky master equation, we consider the gravitational,electromagnetic, and neutrino fields in Schwarzschild spacetime. The free energyand entropy of the spin fields are obtained in terms of the brick-wall model. Itis shown that the entropy of all the spin fields due to the presence of the eventhorizon is proportional to the surface area of the event horizon, and the entropyof the neutrino field is the absolute minimum.
