Evidence of thermodynamics and magnetic monopole plasma formation by photon-magnon interaction in artificial spin ice
D. G. Duarte, S. F. de Souza, L. B. de Oliveira +4
Artificial spin ices (ASI), containing magnetic monopole quasi-particles emerging at room temperature, have been investigated as a promising system to be applied in alternative low…

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…

Emergent magnetic monopole and dipole screening by proximity effect with noble metal
Fernando F. Martins, Teônis S. Paiva, Daniel G. Duarte +4
In this letter we present emergent screening of magnetic monopole and dipole by the presence of 20nm aluminum cover layer. Our results were obtained in base of magnetic atomic forc…
