Naked-eye visualization of geometric frustration effects in macroscopic spin ices
R. S. Gonçalves, A. C. C. Gomes, R. P. Loreto +4
We study planar rectangular-like arrays composed by macroscopic dipoles (magnetic bars with size around a few centimeters) separated by lattice spacing a and b along each direction…
Tuning magnetic charge population and mobility in unidirectional array of nanomagnets as a function of lattice parameters
R. S. Gonçalves, R. P. Loreto, J. Borme +2
Sets of nanomagnets are often utilized to mimic cellular automata in design of nanomagnetic logic devices or frustration and emergence of magnetic charges in artificial spin ice sy…
Manipulation of magnetic skyrmions in a locally modified synthetic antiferromagnetic racetrack
Renan P. Loreto, Xichao Zhang, Yan Zhou +3
In skyrmion-based racetrack memories, the information encoded by skyrmions may be destroyed due to the skyrmion Hall effect, which can be surmounted by using synthetic antiferromag…
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…
Experimental and theoretical evidences for the ice regime in planar artificial spin ices
R. P. Loreto, F. S. Nascimento, R. S. Gonçalves +5
In this work, we explore a kind of geometrical effect in the thermodynamics of artificial spin ices (ASI). In general, such artificial materials are athermal. Here, We demonstrate…
Creation,transport and detection of imprinted magnetic solitons stabilized by spin-polarized current
R. P. Loreto, W. A. Moura-Melo, A. R. Pereira +4
With the recent proposition of skyrmion utilization in racetrack memories at room temperature, skyrmionics has become a very attractive field. However, for the stability of skyrmio…
