Superconducting Spintronic Heat Engine
Clodoaldo I. L. de Araujo, Pauli Virtanen, Maria Spies +7
Heat engines are key devices that convert thermal energy into usable energy. Strong thermoelectricity, at the basis of electrical heat engines, is present in superconducting spin t…
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…
Room temperature two terminal tunnel magnetoresistance in lateral graphene transistor
C. I. L. de Araujo, H. A. Teixeira, O. O. Toro +9
We investigate the behavior of both pure spin and spin-polarized currents measured with four probe non-local and two probe local configurations up to room temperature and under ext…
Anisotropic MagnetoMemristance
Francesco Caravelli, Ezio Iacocca, Gia-Wei Chern +2
In the last decade, nanoscale resistive devices with memory have been the subject of intense study because of their possible use in brain-inspired computing. However, operational e…
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…
