Large non-reciprocal propagation of surface acoustic waves in epitaxial ferromagnetic/semiconductor hybrid structures
A. Hernández-Mínguez, F. Macià, J. M. Hernàndez +2
Non-reciprocal propagation of sound, that is, the different transmission of acoustic waves traveling along opposite directions, is a challenging requirement for the realization of…
Emergence of the stripe-domain phase in patterned Permalloy films
S. Voltan, C. Cirillo, H. J. Snijders +5
The occurrence of stripe domains in ferromagnetic Permalloy (Py=FeNi) is a well known phenomenon which has been extensively observed and characterized. This peculiar…
Quantum dynamics of vortices in mesoscopic magnetic disks
R. Zarzuela, E. M. Chudnovsky, J. M. Hernandez +1
Model of quantum depinning of magnetic vortex cores from line defects in a disk geometry and under the application of an in-plane magnetic field has been developed within the frame…
Magneto-optical imaging of magnetic deflagration in Mn12-Acetate
D. Villuendas, D. Gheorghe, A. Hernández-Mínguez +4
For the first time, the morphology and dynamics of spin avalanches in Mn12-Acetate crystals using magneto-optical imaging has been explored. We observe an inhomogeneous relaxation…
Spatial motion of the magnetic avalanches associated to the CO-AFM to CD-FM transition in LaPrCaMnO manganite
A. Hernández-Mínguez, F. Macià, J. M. Hernandez +4
Very fast magnetic avalanches in (La, Pr)-based manganites are the signature of a phase transition from an insulating blocked charge-ordered (CO-AFM) state to a charge delocalized…
Phonon-Induced Quantum Magnetic Deflagration in Mn12
A. Hernandez-Minguez, F. Macia, J. M. Hernandez +2
A comprehensive set of experiments on the effect of high-frequency surface acoustic waves, SAWs, in the spin relaxation in Mn12-acetate is presented. We have studied the quantum ma…
