Indian scientists have discovered a technical process to use sound waves to reduce energy consumption in next generation technologies, which has potential applications in quantum computing and communication domains.Researchers at Institute of Nano Science and Technology (INST), Mohali, have introduced a new mechanism to generate and control spin currents in electronic devices using surface acoustic waves (SAWs), which are mechanical sound waves that travel along the surface of an elastic material, according to information shared by the Ministry of Science and Technology.In modern technology, there is a growing demand for faster, smaller and more energy-efficient devices. Traditional electronics rely on the movement of electric charge, which leads to heat generation and energy loss.To overcome these limitations, researchers are exploring alternative ways of transmitting information. One promising direction is ‘spintronics’, where information is carried by the spin of electrons instead of an electric charge.In this context, magnons, which are the waves of magnetic disturbances inside materials, are emerging as potential carriers of information. They are particularly attractive because they can operate with much lower energy loss compared to electrons.Shivam Sharma and Prof Abir De Sarkar of INST identified a gap in earlier studies that showed that surface sound waves can influence electron dynamics and that magnon dynamics can be governed by certain external parameters, and developed a new theoretical approach to address the gap.They developed a new analytical model with a two-dimensional ultra-thin material having a graphene-like structure that is magnetic, and studied the effect of surface sound waves on magnon transport.They found that when SAWs travel through a material, they create tiny distortions that influence the motion of magnons, thereby creating a new way to generate spin currents using surface sound waves in two-dimensional magnets.
