In the quantum domain, spins are manifested as the changes of energy levels as observed in the spectral lines in the experimental science of spectroscopy. Since quantum spins are discrete, they only have two possible values, say 'up' and 'down' of Planck's constant divided by 2pi. The following site gives information about the connection between specific heat and the Bose-Einstein or Fermi-Dirac statistical distributions of quantized energy and spin.
