Transport and magnetic properties of magnetic planar nanobridge

We present the results of the study of transport and magnetic properties of magnetic planar nanobridges. A nanobridge (NB) is a single-layer ferromagnetic film structure composed of two wide platforms connected by a narrow channel. Investigation of the magnetic and magnetoresistive properties of the device shows that NB may be useful for spintronic applications. Except the NBs based on conventional ferromagnetics, semiconductor NB is of great interest as combining both spintronic effects and semiconductor technology; besides, quantum ballistic transport effects may appear in it. Magnetic structure of semiconductor NB is also studied.
