Studies on magnetocaloric effect generally concern ferromagnetic materials, due to their high magnetocaloric potential near phase transitions. Recently, this effect on diamagnetic materials was explored and oscillations on the entropy change observed as a consequence of the crossing of the Landau levels through the Fermi energy. The present paper explores the adiabatic temperature change in graphenes and thin films of non-relativistic diamagnetic materials and then compares the results with those from 3D diamagnets. Applying 10T of magnetic field, the temperature change of a gold thin film reaches 1K, while for bulk gold the temperature change is smaller than 6mK. For graphenes, the temperature change reaches 4K with a field of ~1T.
