Electrical detection of spin precession in freely suspended graphene spin valves. The devices are fabricated with a single electron-beam-resist poly(methyl methacrylate) process that minimizes both the fabrication steps and the number of (aggressive) chemicals used, reducing contamination and increasing the yield of the high-quality devices. The method is compatible with almost any contacting material. As-grown devices can present mobilities exceeding 104 cm2 V−1 s−1 at room temperature.
