Query: Specific heat of two-dimensional diluted magnets   Using Monte Carlo techniques, the two-dimensional site-diluted Ising model is
studied. In particular, properties of the specific heat, its critical behaviour
and the emergence of a non-singular maximum above the transition temperature at
moderate concentration of defects, are discussed.
