An Exploration Into Using Ferromagnetic Material and Input Current for Maximizing Uses of Electron Spin

Includes bibliographical references (pages 48-51).The field of spintronics, the manipulation of electron spin and magnetic moment rather than the electron charge, is a growing field that can be applied to enhance electronic devices for communication and computing. In 1980, after the discovery of giant magnetoresistance by Peter Grunberg and Albert Fert, the field of spintronics was started. The layers of\ud ferromagnetic and nonmagnetic material to control electron spin and therefore, creating magnetic precession in devices called Spin Torque Nano-Oscillators, are used to generate a microwave signal. The power output of coupled oscillators, as compared to the uncoupled oscillators increases by the amount of oscillators squared. However, for an increase in coupled oscillators, the regions of synchronization decreases. Therefore, in this paper we explore the synchronization of the system for varying values of input DC current, a coupling parameter in the system
