Abstract
GaMnAs Digital Alloys have recently drawn the attention of various workers, due to their very special properties from the point of view of applications in spintronics. Physics and Novel Concepts of GaMnAs Digital Alloys have been presented in this paper. The various technical aspects of digital alloys like III1-xMnxV Random Alloys (InMnAs and GaMnAs), MBE grown GaMnAs Random Alloys, Photo-induced Ferromagnetism, Magnetization Measurements, MagnetoTransport Measurements, and Temperature Dependence of Sheet Resistance have been presented. Some of the important related studies have also been reviewed. Some ideas about other useful digital alloys have also been incorporated. It has been highlighted how crucial these materials are for spintronic devices. The material presented in this paper is expected to be of some use to the new researchers entering this field and the designers and technologists engaged in the fabrication of spintronic devices by using GaMnAs digital alloys.
