The quantum impact of magnetic and optical effects on electrical properties exhibited by multiwall carbon nanotubes decorated with bimetallic nanoparticles integrated by platinum and nickel was analyzed. An external magnetic field causes sensitive magneto-quantum conductivity in the samples and it can be described by the Aharonov-Bohm effect. The nature of the nanoparticles decorating the carbon nanostructures shifted the characteristic quantum response for the magneto-conductive measurements. Magnetically-controlled changes in optical phonons were considered to be responsible for the bistable hysteretic system. A laser-induced-phononic process derives in a strong modification of the electrical properties exhibited by the sample.
