Excessive energy dissipation in CMOS devices during switching is the primary threat to continued downscaling of computing devices in accordance with Moore's law. In the quest for alternatives to traditional transistor based electronics, nanomagnet-based computing [1, 2] is emerg…

The Co-Pt systems have been extensively studied because of their potential applications in spintronic devices. We have experimentally measured transport spin polarization (PC ) using Point Contact Andreev Reflection (PCAR) spectroscopy and magnetic properties of Co1-x Pt x alloy…

Aggressive scaling of Silicon CMOS feature size has led to increased integration density and improved system performance. However, when scaling approaches its fundamental limit, it is extremely difficult to carry it further along Moore's law curve. To meet the continuously incre…

Spintronics would utilize the spin of the electron for information processing and storage, leading to devices that may be smaller, faster, and more energy-efficient than their electronic counterparts. Before these spin-based devices can be fully realized, we must answer the foll…

Dilute magnetic semiconductors (DMSs) are attractive. They are candidate materials for applications in novel spintronic devices. Because of the giant Zeemaneect in the paramagnetic state, a magnetic eld can be used to manipulate the spin and charge of carriers in DMSs. One possi…
