AI Article Synopsis
- Organic radicals are being explored as potential components for organic magnets and spintronic devices.
- Researchers demonstrated that a film made from organic radicals can emit spin currents at room temperature through a process called spin pumping.
- This study showcases a stable Blatter-type radical that, when paired with a ferromagnetic layer, can reversibly adjust spin current emissions, paving the way for new metal-free organic spintronic applications.
Article Abstract
Organic radicals have long been suggested as candidates for organic magnets and components in organic spintronic devices. Herein, we demonstrate spin current emission from an organic radical film via spin pumping at room temperature. We present the synthesis and the thin film preparation of a Blatter-type radical with outstanding stability and low roughness. These features enable the fabrication of a radical/ferromagnet bilayer, in which the spin current emission from the organic radical layer can be reversibly reduced when the ferromagnetic film is brought into simultaneous resonance with the radical. The results provide an experimental demonstration of a metal-free organic radical layer operating as a spin source, opening a new avenue for the development of purely organic spintronic devices and bridging the gap between potential and real applications.
