Low-loss YIG-based magnonic crystals with large tunable bandgaps

Low-loss YIG-based magnonic crystals with large tunable bandgaps

Control of spin wave transport in magnonic crystals is vital for magnonic devices. Here the authors show low-loss spin-wave manipulation in nanometer thick magnonic crystals of discrete YIG stripes separated by air or CoFeB filled grooves exhibiting tunable bandgaps of 50–200 MHz.
