Surface acoustic wave coupled to magnetic resonance on a multiferroic CuB${}_2$O${}_4$

R. Sasaki, Y. Nii, Y. Onose

We observed surface acoustic wave (SAW) propagation on a multiferroic material CuB${}_2$O${}_4$ with use of two interdigital transducers (IDTs). The period of IDT fingers is as short a…
