  Critical temperatures for the ferro-paramagnetic transition in the Ising
model are evaluated for five Archimedean lattices, basing on Monte Carlo
simulations. The obtained Curie temperatures are 1.25, 1.40, 1.45, 2.15 and
2.80 [J/k_B] for (3,12^2), (4,6,12), (4,8^2), (3,4,6,4) and (3^4,6) lattices,
respectively.
