“Spin waves” are one of the options to replace the transfer of electronic charges in logic devices to make information processing faster and more efficient. The Spin-Wave Voices installation allows us to explore, sense, and interact with this emerging technology. With a simple pedal activation, it is possible to start an excitation of spin waves in one of various microstructures of different shapes. As the pedal is pressed, micromagnetic simulations of the real structure, which were confirmed by synchrotron measurements, are visualized and sonified. Although they are extremely fast and small in real life, the waves are slowed down and magnified billions of times at the installation in order to make them accessible to human perception. Altogether, that allows us to see and to hear the Spin-Wave Voices as they appear, evolve, and differ depending on the shape. The posters explaining the scientific background and a microscope showing how small the real structures are will allow visitors to explore the concept in more depth.
