Spintronics is based on manipulating the flow of spin polarized current in metals and semiconductors. Introducing spin degrees of freedom and charge into the present semiconductor electronics at nanoscale level is a very important issue for realizing novel devices. Research is being carried out for the development of magnetic random access memories and nonvolatile logic applications by extensively studying novel spin based semiconductor device structures and magnetic material semiconductor hybrid
endless. One of the most fascinating concepts in the sub-atomic universe is the idea of spintronics. Spintronics is the quantum study of the independent angular momentum (not to be confused with the orbital angular momentum of the electron) of a particle, typically that of an electron (Introduction). An electron is a fundamental particle, with a negative charge, and is independently studied in the process of spintronic devices. The spin angular momentum of electrons is ±½ћ. Devices that use the properties
contracts helped NVEC develop an intellectual property portfolio and accumulate over 50 patents regarding spintronic and MRAM technology. Recently the company has reduced their dependence on research contracts and has grown tremendously through product sales, averaging an increase of 25% top-line growth the past three years. The company develops and sells products that utilize “spintronics”, a nanotechnology which relies on electron spin rather than electron charge to gather, store and send information
Nanocrystalline perovskite and spinel magnetic mixed oxides materials have gained immense importance due to their novel properties, which are significantly different from those of their bulk counterparts [1]. Nanocrystals of spinel ferrites, with general formula MFe2O4 (where M = Ni, Cu and Zn) are most interesting class of magnetic materials due to its facinating properties such as low melting point, high spectfic heat, large expansion coefficent and low magnetic transition temperature[2,3]. Because
1. INTRODUCTION 1.1. Definition Condensed Matter Physics is branch of physics that deals with the physical properties of condensed matter such as liquids and solids. This branch of study seeks to understand the behavior of condensed phases of matter by using established laws of physics. [Taylor, Philip L. 2002] Liquids and solids are the most well-known forms of condensed matter but there are others particularly as a result of quantum physics. Condensed matter physics asserts to atoms as closer
