Abstract

During the visit of Prof. Dr. Carlos Ramos, experiments on Ferromagnetic Resonance (FMR) and microwave absorption in NiFe antidots thin films with various thickness and pores diameters will be performed. The samples utilized in this program will be fabricated at the "Low Temperature Laboratory (LMBT)" and at "Atomic Center of Bariloche (CAB)". It is planned to fabricate (using sputtering technique onto the alumina anodized membranes surface) at least 5 samples with thickness varying from 10 to 80 nm and pore diameter from 35 to 200 nm. The experiments will be performed at room temperature varying the orientation between the magnetic applied field and the sample plane, in order to characterize the microwaves absorptions. (AU)
