In contrast to electrical currents magnon spin currents conduct magnetic momenta. One fundamental building block of magnon spintronics is magnon logic, by which logic operations are processed by the superposition of spin currents. An international team of researchers (Germany, Japan) reports on magnetization orientation-dependent spin current detection signals in collinear magnetic multilayers inspired by the functionality of a conventional spin valve. This yielded a spin valve-like behavior with an amplitude change of 120% in their systems… read more. Open access TECHNICAL ARTICLE
Depending on the magnetic configuration of the spin valve, the electrical signal is transmitted (bottom) or suppressed (top). Credit: Joel Cramer
