Abstract: Planar phase shifters fabricated based on ferrite-ferroelectric layered structures are studied experimentally. The structures served as waveguides for spin-electromagnetic waves, whose phase shift was controlled by both electric and magnetic fields. The measurements were performed in the magnetic field range from 900 to 2100 Oe, which corresponds to operating frequencies from 4.0 to 8.5 GHz, with 5- to 20-$\mu$m-thick yttrium-iron garnet ferrite films and 200- to 500-$\mu$m-thick barium-strontium titanate ferroelectric plates. It is shown that the phase shift may exceed 180$^\circ$ and is a function of the magnetic and electric fields and also of the thickness of the ferrite and ferroelectric layers.
