摘要：
Superlattices of Gd/GdN were grown on silicon substrates with different thickness ratio between nanolayers of Gd and GdN. Films were characterized through XRD, XPS and magnetization measurements. Results indicate that different multilayer arrangements, with layers between 5 and 20 nm thickness, promote: (1) a broadening of the peak of isothermal magnetic entropy change around 250-270 K and (2) the emergence of a second peak around 70 K.
