Quantifying ground state degeneracy in planar artificial spin ices: the magnetic structure factor approach
F. S. Nascimento, L. B. de Oliveira, D. G. Duarte +3
Magnetic structure factor (MSF) is employed to investigate the ground state degeneracy in rectangular-like artificial spin ices. Our analysis considers the importance of nanoisland…
Direct observation of magnetic monopole freedom in two-dimensional artificial spin ice
D. G. Duarte, L. B. de Oliveira, F. S. Nascimento +4
Magnetic monopole unpairing as a function of external magnetic fields is presented as a fingerprint of this emergent quasiparticles freedom in a two-dimensional artificial spin ice…
Dirac-Surface-State-Dominated Spin to Charge Current Conversion in the Topological Insulator Films at Room Temperature
J. B. S. Mendes, O. Alves-Santos, J. Holanda +6
We report the spin to charge current conversation in an intrinsic topological insulator (TI) film at room temperature. The spin currents are generated…
Circular single domains in hemispherical small size Permalloy clusters
Clodoaldo I. L. de Araujo, Jakson M. Fonseca, João P. Sinnecker +3
We have studied ferromagnetic Permalloy clusters obtained by electrodeposition on n-type silicon. Magnetization measurements reveal hysteresis loops almost independent on temperatu…
Realization of magnetic monopoles current in an artificial spin ice device: A step towards magnetronics
R. P. Loreto, L. A. Morais, R. C. Silva +5
Magnetricity- the magnetic equivalent of electricity- was recently verified experimentally for the first time. Indeed, just as the stream of electric charges produces electric curr…
