Tunneling anisotropic magnetoresistance in antiferromagnetic tunnel junctions
Tunneling anisotropic magnetoresistance (TAMR) in antiferromagnetic tunnel junctions is a magnetoresistance effect driven by spin-orbit coupling, where resistance depends on the Néel vector's orientation rather than electrode alignment.
Tunneling endoscopic resection
Tunneling endoscopic resection, also called submucosal tunneling endoscopic resection, is a minimally invasive endoscopic technique that removes esophageal tumors through a tunnel under the mucosa.
Tunneling magnetoresistance
Tunneling magnetoresistance (TMR) is the resistance change in a magnetic tunnel junction when its electrodes' magnetizations switch between parallel and antiparallel alignment; first observed by Michel Jullière in 1975.
Tunneling protocol
A tunneling protocol is a network protocol that encapsulates packets of one protocol inside another so data can cross a network that does not natively support the carried protocol.
