Scientific Image - Nanoscale Interface for Spin Injection
| Content Provider | National Informal STEM Education Network (NISE Net) |

| Description | This is a scanning electron micrograph of a nanoscale interface for spin injection in a nanomechanical torsion oscillator used for measuring tiny amounts of torque. This interface is built on a silicon-based nanomechanical torsion oscillator, a device used to measure tiny amounts of torque. The device contains a central wire running from top left to bottom right. The top surface of one part of this wire is coated with a 50 nm layer of cobalt (which is magnetic); the top surface of the other part is coated with 50 nm of non-magnetic gold. As electrons travel from the magnetic into the non-magnetic part of the nanowire, they flip their spin directions, causing mechanical twisting of the wire. • SIZE: The diameter of the nanowire at center is about 100 nm. • IMAGING TOOL: Scanning electron microscope |
