Energy-efficient domain wall motion governed by the interplay of helicity-dependent optical effect and spin-orbit torque [PDF]
, 2019 Spin-orbit torque provides a powerful means of manipulating domain walls along magnetic wires. However, the current density required for domain wall motion is still too high to realize low power devices.

Spin-Torque Generation in Topological-Insulator-Based Heterostructures [PDF]
, 2016 Heterostructures utilizing topological insulators exhibit a remarkable spin-torque efficiency. However, the exact origin of the strong torque, in particular whether it stems from the spin-momentum locking of the topological surface states or rather from ...

Spin-Transfer Torque Switching at Ultra Low Current Densities
MATERIALS TRANSACTIONS, 2015 The influence of the tantalum buffer layer on the magnetic anisotropy of perpendicular Co-Fe-B/MgO based magnetic tunnel junctions is studied using magneto-optical Kerr-spectroscopy. Samples without a tantalum buffer are found to exhibit no perpendicular magnetization.

Disk-satellite interaction in disks with density gaps
, 2012 Gravitational coupling between a gaseous disk and an orbiting perturber leads to angular momentum exchange between them which can result in gap opening by planets in protoplanetary disks and clearing of gas by binary supermassive black holes (SMBHs ...

Limited Angle Torque Motors Having High Torque Density, Used in Accurate Drive Systems
Acta Polytechnica, 2011 A torque motor is a special electric motor that is able to develop the highest possible torque in a certain volume. A torque motor usually has a pancake configuration, and is directly jointed to a drive system (without a gear box). A limited angle torque motor is a torque motor that has no rotary electromagnetic field — in certain papers it is referred
