Controlled switching between paramagnetic and diamagnetic Meissner effect in Pb/Co nanocomposites
Y. T. Xing, H. Micklitz, T. G. Rappoport +1
A hybrid system which consists of a superconducting (SC) Pb film (100 nm thickness) containing 1 vol% single domain ferromagnetic (FM) Co particles of mean-size 4.5 nm…
Ion-beam modification of the magnetic properties of GaMnAs epilayers
E. H. C. P. Sinnecker, G. M. Penello, T. G. Rappoport +5
We study the controlled introduction of defects in GaMnAs by irradiating the samples with energetic ion beams, which modify the magnetic properties of the DMS. Our study focuses on…
Static and dynamic properties of vortices in anisotropic magnetic disks
Tiago S. Machado, Tatiana G. Rappoport, Luiz C. Sampaio
We investigate the effect of the magnetic anisotropy () on the static and dynamic properties of magnetic vortices in small disks. Our micromagnetic calculations reveal that fo…
Spontaneous vortex phases in ferromagnet-superconductor nanocomposites
Y. T. Xing, H. Micklitz, T. G. Rappoport +3
The interplay between superconductivity and magnetism gives rise to many intriguing and exciting phenomena. In this Letter we report about a novel manifestation of this interplay:…
