The magnetoresistance of Fe/MgO/Fe magnetic tunnel junctions (MTJs) was studied taking into consideration image forces. For MTJs with an MgO insulator, explanations are given of the giant tunneling magnetoresistance (TMR) effect and the effect of the increasing TMR with an increase in MgO insulator thickness. It is demonstrated that the electron current density through MTJs can be high enough to switch the magnetization of a ferromagnetic electrode.

Electron Current Density

Abstract An accurate photographic method for measuring intensities on a fluorescent screen is described. Simultaneously with the fluorescent screen a calibrated 7-step grey scale is recorded on the film. Using a scanning photometer the intensity distribution can be digitized and by comparison with the grey scale converted to electron current density. As an example LEED-intensities from a Si (lll)-surface obtained with the photographic technique are compared with spot-photometer measurements.
