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…

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…
