Collective oscillation of spins in magnetic lattice known as spin waves (magnons) possess relatively long coherence length at room temperature, which makes it possible to build submicrometer scale holographic devices similar to the devices developed in optics. In this paper, we present a prototype 2-bit magnonic holographic memory. The memory consists of(More)
In this paper, we present recent developments in magnonic holographic memory devices exploiting spin waves for information transfer. The devices comprise a magnetic matrix and spin wave-generating/detecting elements placed on the edges of the waveguides. The matrix consists of a grid of magnetic waveguides connected via cross junctions. Magnetic memory(More)
In this work, we consider the possibility of building magnonic holographic read-only memory (MH-ROM) devices exploiting spin-wave interference for readout. MH-ROM consists of a grid of magnetic waveguides connected via cross junctions. Some of the cross junctions have a hole in the center of junctions, whereas others do not. The presence/absence of the hole(More)
In this paper, we present the most recent results on the development of magnonic holographic memory (MHM). MHM is a type of holographic device, which uses spin waves for data transfer and processing. The most appealing properties of MHM include parallel read-out and database search. We present experimental data showing parallel read-out of four magnetic(More)
