Novel non-reciprocal microwave spin wave and magneto-elastic wave devices for on-chip signal processing

The discovery of interfacial Dzyaloshnskii-Moriya interaction (DMI) enables development of novel ultra-compact non-reciprocal devices for microwave signal processing. Such devices are based on control of spin waves and magneto-elastic waves by electric field and addition of ultra-thin layers of heavy metals to the devices. Here we discuss recent advances in the development of such devices, which can be used for implementation of on-chip non-reciprocal microwave devices.
