Magnetic fluids belong to the class of nanomaterials with a high gain light absorption, aggregative and sedimentation stability as well controllability by external fields, which is interest use in field optoacoustics. The purpose work was experimentally study effect optoacoustic transformation magnetic fluid, depending on concentration colloidal particles, boundary conditions, intensity laser i...

The generation of nonequilibrium electron spin polarization, transport, and detection are fundamental in many quantum devices. We demonstrate that a lattice magnetic nanodots enhances the polarization monolayer graphene via carrier exchange. probed through resistively detected variant resonance observed amplification mediated by presence nanodots. Each nanodot locally injects surplus spin-polar...
