Self-hybridization and tunable magnon-magnon coupling in van der Waals synthetic magnets

J Sklenar, W Zhang - Physical Review Applied, 2021 - APS
Van der Waals magnets are uniquely positioned at the intersection between two-
dimensional materials, antiferromagnetic spintronics, and magnonics. The interlayer …

Nematic versus ferromagnetic spin filtering of triplet Cooper pairs in superconducting spintronics

A Moor, AF Volkov, KB Efetov - Physical Review B, 2015 - APS

Stimulation of a singlet superconductivity in SFS weak links by spin–exchange scattering of Cooper pairs

AV Samokhvalov, RI Shekhter, AI Buzdin - Scientific Reports, 2014 - nature.com
Josephson junctions with a ferromagnetic metal weak link reveal a very strong decrease of
the critical current compared to a normal metal weak link. We demonstrate that in the ballistic …
