The piezoelectric component is a key feature. So the film strains from process and mechanical shocks should not be treated lightly.

Very intesting work. What are manufacturing challanges for this technology? Can they make some storage device for performance comparision to exsisting device?

I was surprised by that width as also shown in the photo. I would have thought they could go smaller (submicron).

no, I think 5um refers to a width of the waveguide

So the spin wave wavelength is on the order of 5 microns?
