Switching nanomagnets using infrared lasers

Researchers at Graz University of Technology have demonstrated that infrared lasers can induce nanomagnets by exciting molecular vibrations in metal phthalocyanine molecules. These vibrations create localized magnetic fields in the nanometer range, which can be controlled by manipulating the infrared light. This discovery holds potential for developing high-precision optical switches and circuits for quantum computing. The team plans to further explore the practical application of this phenomenon by placing these molecules on surfaces and optimizing the support materials.
