 Oxides For Spintronics: A Review Of Engineered Materials For Spin Injection

Megan C. Prestgard, Gene P. Siegel and Ashutosh Tiwari

DOI: 10.5185/amlett.2014.amwc1032

Keywords: Spintronics; diluted magnetic semiconductors; diluted magnetic dielectric; ferromagnetism.

Abstract: 

In this article we have reviewed the role of oxides in spintronics research, and specifically how these materials stand to further improve the efficiencies and capabilities of spin injection for active spintronic device development. The use of oxides in spintronics is advantageous in that they are stable in air, can be easily modified, and can possess a wide variety of properties which are beneficial to spintronics applications. This paper delineates the progression of spintronics and shows how applying oxide systems, in the form of half-metallic LaSrMnO3, the diluted magnetic semiconductor ZnO:Co, and diluted magnetic dielectrics CeO2:Co and Sm2O3:Co, has influenced and improved spintronics capabilities. An outline of the future potential for oxides in the realm of organic spintronic devices is also given.
