Hybrid materials composed of inorganic magnetic cobalt-manganese mixed nanoferrites and PMMA polymeric shell have been fabricated by applying an in-situ polymerization process using pre-prepared inorganic core particles (8-9 nm). The ability of the hybrid heating under action of alternating magnetic field and laser radiation (in a separate and synergy mode) was evaluated and compared with stock nano-particles. It was found that hybrid materials show a high response to both stimulants and the highest temperature was achieved by using both AMF and laser exposure under synergic mode (twice the value for the AMF alone). The specific absorption rate of composite material was around 30 W/g for the optimized field parameters and both laser wavelengths (808 and 1122 nm). The great response of the hybrid material for contactless action of AMF and NIR radiation makes the proposed material very interesting for future biomedical and EMI shielding applications.
