Mancilla Almonacid, D.; Arias Federici, Rodrigo (Amer Physical Soc., 2016)The stability of the magnetization auto-oscillations of the ferromagnetic free layer of a cylindrical nanopillar structure is studied theoretically using a classical Hamiltonian formalism for weakly interacting nonlinear ...
-
Arias Federici, Rodrigo (IEEE, 2015)Magnetostatic modes in ferromagnetic samples have been studied systematically since the 1950s. They are very well characterized and understood in samples with uniform internal magnetic fields. More recently, interest has ...

Langer, M.; Wagner, K.; Sebastian, T.; Huebner, R.; Grenzer, J.; Wang, Yutian; Kubota, T.; Schneider, T.; Stienen, S.; Lenz, K.; Schultheiss, H.; Lindner, J.; Takanashi, K.; Arias Federici, Rodrigo; Fassbender, J. (AMER INST PHYSICS, 2016)An all-electrical method is presented to determine the exchange constant of magnetic thin films using ferromagnetic resonance. For films of 20 nm thickness and below, the determination of the exchange constant A, a fundamental ...

Ramírez Bustamante, Adán Esteban (Universidad de ChilePrograma Cybertesis, 2008)En esta tesis se estudia el fenómeno que es conocido en la literatura como “efectos de tamaño y geometría en fenómenos de transporte”. En específico se estudia de qué manera la superficie rugosa, que limita la estructura ...

Arias Federici, Rodrigo; Maradudin, Alexei A. (Optical Society of America, 2013-04)On the basis of a rigorous, nonperturbative, purely numerical solution of the corresponding reduced Rayleigh equation for the scattering amplitudes we have studied the scattering of a surface plasmon polariton by a two ...

Duan, Zheng; Krivorotov, Ilya N.; Arias Federici, Rodrigo; Reckers, Nathalie; Stienen, Sven; Lindner, Jürgen (Amer Physical Soc, 2015)We report experimental and theoretical studies of spin wave eigenmodes in transversely magnetized thin film Permalloy wires. Using broadband ferromagnetic resonance technique, we measure the spectrum of spin wave eigenmodes ...
-
Mancilla Almonacid, D.; Arias Federici, Rodrigo (American Physical Society, 2017)The excitation of the linear spin wave modes of a soft ferromagnetic free layer of a nanopillar structure through dc-ac currents that traverse the structure is studied, as well as with ac magnetic fields. There is interest ...

Shlomai, H.; Adda-Bedia, M.; Arias Federici, Rodrigo; Fineberg, Jay (Amer Geophysical Union, 2020)We experimentally and analytically explore supershear ruptures that are excited at the onset of frictional motion within "bimaterial interfaces," frictional interfaces formed by contacting bodies having different elastic ...

Mancilla Almonacid, D.; Arias Federici, Rodrigo; Oyarzún, S.; Altbir, D.; Allende, S. (American Physical Society, 2017)A detailed analytical and numerical study of the spin wave modes of the free layer of a nanopillar spin torque nano-oscillator (STNO) has been performed as a function of the magnetostatic interaction between the free and ...
