Summary:
High-resolution measurements of the specific heat, C, near the ferromagnetic phase transition of the diluted ferromagnetic system Eux Srl_xO are reported. Samples with four different concentrations (x = 1, x =0.9, x =0.7 and x =0.5) have been studied and the expected phase diagram, i.e. the linear decrease of T~ with decreasing x, is confirmed. Our specific-heat data of the pure EuO samples yield a critical exponent e = -0.12_+ 0.02 in contrast to literature results, but in agreement with the value expected theoretically for this three-dimensional Heisenberg system. The origin of the discrepancies is traced down to differences in data analysis.
