The effect of nanosecond laser pulses (λ=1064 nm) on the optical properties of onion-like carbon (OLC) prepared by high-temperature vacuum annealing of detonation nanodiamond and dispersed in N,N-dimethylformamide (DMF) is studied. It is established, that the interaction between laser pulses and OLC suspension results in the suspension bleaching in the interaction point. The bleached fraction of the suspension is pushed out from inhomogeneous magnetic field. The observed behavior can be explained by laser-stimulated chemical reactions between OLC and DMF, which lead to the formation of a new substance with pronounced diamagnetic properties. Relying on the effect discovered the model of magnetically controlled optical switch is supposed.
