Аннотация:This article shows that in layered structures representing thin (∼2 μm) cobalt, nickel and permendur layers on ferroelectric ceramics substrates (∼400 μm) the elastic strains at the interface make a more significant contribution to the magnetoelectric effect than the ferromagnetic layer magnetostriction. For obtaining these structures the ion-beam sputtering – deposition after ion-beam planarization of the substrate surface was used. The magnetoelectric voltage coefficient at a frequency of an alternating magnetic field of 1 kHz at room temperature for structures with cobalt is higher than that for structures with nickel and permendur. The structures obtained are thermostable within the temperature range from −25 to +120 °C and have reproducible magnetoelectric properties. These structures can find their application as magnetoelectric converters and magnetic fields sensors.
