  We show that the magnetic moment of a nanoparticle embedded in the surface of
a solid can be switched by surface acoustic waves (SAW) in the GHz frequency
range via a universal mechanism that does not depend on the structure of the
particle and the structure of the substrate. It is based upon generation of the
effective ac magnetic field in the coordinate frame of the nanoparticle by the
shear deformation of the surface due to SAW. The magnetization reversal occurs
via a consecutive absorption of surface phonons of the controlled variable
frequency. We derive analytical equations governing this process and solve them
numerically for the practical range of parameters.
