Fundamental interactions are the basis of the most diverse phenomena in science that allow the dazzling of possible applications. In this work, we report a new interaction, which we call chemical-quantum-magnetic interaction. This interaction arises due to the difference in valence that the Fe3O4/PANI nanostructure acquires under certain conditions. In this study, PANI activates the chemical part of the oscillations, leaving the quantum and magnetic part for the double valence effect and consequently for changing the number of spins of the nanostructure sites. We also observed using interaction measurements that chemical-quantum-magnetic interactions oscillate in a subcritical regime satisfying the behavior of a damped harmonic oscillator.
