Parallel data processing with Magnonic Holographic Co-Processor

Abstract

In this work, we present experimental data demonstrating the capabilities of Magnonic Holographic Co-Processor for parallel data processing. It is a type of magnetic logic device, which utilizes spin waves for data transfer and processing. Its operation is based on the correlation between the phases and the amplitudes of the input spin waves and the output inductive voltages. We present experimental data obtained for 8-terminal prototype based on Y3Fe2(FeO4)3 structure. The input of the device is provided by the phased array of spin wave generating elements allowing us to produce input phase patterns of an arbitrary form. The obtained data demonstrate the capabilities of Magnonic Holographic Co-Processor for parallel data processing by using spin wave superposition. Potentially, magnonic holographic devices can be implemented as complementary logic units to digital processors. Physical limitations and technological constrains are also discussed.
