Tiwari, Ashutosh | Shape of the Hanle curve in spin-transport structures in the presence of an ac drive | Resistance between two ferromagnetic electrodes coupled to a normal channel depends on their relative magnetizations. The spin-dependent component, R, of the resistance changes with magnetic field, B, normal to the directions of magnetizations. In the field of spin transport, this change, R(B), orig... | | 2014-01-01 |
