【 摘 要 】

The microwave properties of multiferroic magnonic crystals based on a width-modulated slot-line were investigated theoretically for the first time. Dispersion characteristics of spin-electromagnetic waves propagating in the heterostructures were calculated. It was shown that band gaps in the spin-electromagnetic wave spectrum are controlled with both electric and magnetic fields.
