Team develops world's most powerful nanoscale microwave oscillators
Schematic representation of a spin-transfer nano-oscillator (STNO) with free and pinned magnetic layers (left), and a scanning-electron-microscopy (SEM) image of a cross-section of an STNO (right), showing top and bottom metallic electrodes used for electrical connections. The lateral size of the STNO is about 100nm. Continue reading
