  We explore various temperature dependencies and thermodynamic quantities of a
mean field model of a ferromagnetic-superconducting system. The starting point
for this model is based on an s-wave pairing scheme in the singlet channel of
the superconducting state and a spontaneously broken symmetry phase in the
ferromagnetic state. We show numerically and analytically that a state of
coexistence reveals itself and is favored energetically over other possible
states, and a simple phase diagram is developed. Finally, a comparison of the
specific heat with experiment is shown.
