Spin transport measured through molecular films now long enough to develop spintronic devices

Information processing devices such as smartphones are becoming more sophisticated because their information-recording density constantly increases, thanks to advances in microfabrication technology. In recent years, however, we are rapidly approaching the physical limits to processing, making further miniaturization difficult. Perhaps, though, the continued demand for more sophisticated technology requires a fundamental change in operating principles, so that faster, smaller, new devices can continue to be made.
