Quantum Correction to Entropy of the Kerr Black Hole due to Rarita-Schwinger Fields

Quantum correction to entropy of the Kerr black hole arising from Rarita-Schwinger fields is studied by using the Newman-Penrose formalism and brick-wall model. It is shown that contribution of spin to the logarithmic term of the quantum correction is dependent on both the square of spin of the particle and the rotation of the black hole. For different values of a/r₊, the subleading term can increase or decrease, or cannot affect the entropy.
