This paper proposes a protocol for the electrical detection of a magnetic skyrmion via the
change of the tunneling magnetoresistive (TMR) signal in a three-terminal device. This
approach combines alternating spin-transfer torque from both spin-filtering (due to a
perpendicular polarizer) and spin-Hall effect with the TMR signal. Micromagnetic
simulations, used to test and verify such working principle, show that there exists a
frequency region particularly suitable for this achievement. This result can be at the basis of …
