Theoretical prediction of a giant anisotropic magnetoresistance in carbon nanoscrolls [Ching Hao Chang]

【107 MOE Yushan Young Scholars Program】Special Issue

Anisotropic magnetoresistance (AMR) phenomenon has triggered great interest since the development of AMR sensors for magnetic recording. In classical iron, cobalt and nickel alloys this effect originates from an anisotropy in electron scattering due to spin-orbit interaction (SOI). Although the AMR effect has found many applications in magnetic recording and sensor devices, its magnitude lies in the 1% range for typical transition metals and their alloys. ...
