Magneto-transport properties in Fe thin films in an external electric field (E-field) were investigated by means of the first-principles full-potential linearized augmented plane-wave method. Results for an Fe monolayer predict a reduction (enhancement) in the in-plane dc electric (intrinsic Hall) conductivity due to a change in the band structure around the Fermi energy when the E-field is introduced. In addition, a magnetization reorientation from the out-of-plane direction to the in-plane direction leads to an abrupt change in the conductivity. Modification of the ac electric conductivity by an E-field is also presented.
