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…
Vortex-crystal pattern in an anti-artificial spin ice system
C. I. L. de Araujo, R. C. Silva, I. R. B. Ribeiro +6
We have proposed in this work an original system composed by anti-dots nanopatterned in a ferromagnetic thin film, mimicking negatively the structure of an articial spin ice. In th…
From confinement to deconfinement of magnetic monopoles in artificial rectangular spin ices
F. S. Nascimento, L. A. S. Mól, W. A. Moura-Melo +1
We study a frustrated two-dimensional array of dipoles forming an artificial rectangular spin ice with horizontal and vertical lattice parameters given by and respectively.…
Magnetic anisotropy of elongated thin ferromagnetic nano-islands for artifical spin ice arrays
G. M. Wysin, W. A. Moura-Melo, L. A. S. Mól +1
The energetics of thin elongated ferromagnetic nano-islands is considered for some different shapes, aspect ratios, and applied magnetic field directions. These nano-island particl…
Thermodynamics of elementary excitations in artificial magnetic square ice
R. C. Silva, F. S. Nascimento, L. A. S. Mól +2
We investigate the thermodynamics of artificial square spin ice systems assuming only dipolar interactions among the islands that compose the array. The emphasis is given on the ef…
