Abstract : We present crossover calculations for the susceptibility and specific heat of disordered ferromagnets. We show that the critical behaviour in the experimental temperature range is governed by the unstable fixed point of strongly diluted magnets. The asymptotic behaviour is found only in a narrow region around Tc.
