Hall Effect Spintronics

Abstract

Following the original project continued research devoted to manufacture, study and optimization of materials suitable for spintronics applications based on the extraordinary Hall effect (EHE). The work was focused on three major tasks: 1. Preparation and study of CoPd multilayers for the Extraordinary Hall Effect based magnetic memory. 2. Development of a novel and effective experimental technique for determination of anisotropy constants in ultra-thin magnetic films with out of- plane magnetic anisotropy. 3. Search for magnetic reversal mechanisms stimulated by unpolarized electric current. This work produced the following three publications. A second grant commenced to continue this work under FA8655-11-1-3081. 1. D. Rosenblatt, M. Karpovski and A. Gerber, Reversal of the Extraordinary Hall Effect polarity in thin Co-Pd multilayers., Appl. Phys. Lett., 96, 022512 (2010). 2. D. Rosenblatt, M. Karpovski and A. Gerber, Monitoring magnetization reversal and perpendicular anisotropy of ferromagnetic films by the extraordinary Hall effect and anisotropic magnetoresistance., Jour. Appl. Phys. 108, 043924 (2010). 3. O.Riss, A.Gerber, I.Ya.Korenblit, M.Karpovsky, S. Hacohen-Gourgy, A.Tsukernik, J.Tuaillon-Combes, P. Melinon, and A.Perez, Non-thermal magnetization reversal assisted by unpolarized current., Phys. Rev. B 82, 144417 (2010).
