Radar shielding experiments by composite bilayer magnetic systems
Jaume Calvo-de la Rosa, Jesús López-Sánchez, Joan Manel Hernàndez +2
An experimental strong increase of the reflection loss (from 25 up to 35 dBs) and an extension of the absorption bandwidth up to 20% is measured in a set of novel functional bilaye…
Microwave absorption in barium hexaferrite nanocomposites with random anisotropy
Jaume Calvo-de la Rosa, Antoni García-Santiago, Joan Manel Hernàndez +3
This work reports experimental evidence of random magnetic behavior observed in modified barium hexagonal ferrites. We observe a significant transition in the magnetic properties o…
Resonant and off-resonant magnetoacoustic waves in epitaxial FeSi/GaAs hybrid structures
Marc Rovirola, M. Waqas Khaliq, Blai Casals +6
Surface acoustic waves (SAWs) provide an efficient dynamical coupling between strain and magnetization in micro/nano-metric devices. Using a hybrid device composed of a piezoelectr…
Effects of the Zhang-Li Torque on Spin Torque nano Oscillators
Jan Albert, Ferran Macià, Joan Manel Hernàndez
Spin-torque nano-oscillators (STNO) are microwave auto-oscillators based on magnetic resonances having a nonlinear response with the oscillating amplitude, which provides them with…
Generation and imaging of magnetoacoustic waves over millimetre distances
Blai Casals, Nahuel Statuto, Michael Foerster +7
Using hybrid piezoelectric/magnetic systems we have generated large amplitude magnetization waves mediated by magneto-elasticity with up to 25 degrees variation in the magnetizatio…
Generation and stability of dynamical skyrmions and droplet solitons
Nahuel Statuto, Joan Manel Hernàndez, Andrew D. Kent +1
A spin-polarized current in a nanocontact to a magnetic film can create collective magnetic oscillations by compensating the magnetic damping. In particular, in materials with unia…
