Abstract: The invention relates to the field of ceramics and relates to a piezoelectric component having a magnetic layer, which can be used, for example, as a resistor component, as a switch element or control or memory element or as a sensor. The invention discloses a piezoelectric component having a magnetic layer, with which the electrical and magnetic properties of the thin film(s) located thereon can be modified by mechanical elongation. In embodiments, a piezoelectric component with magnetic layer which comprises the piezoelectric compound (1-x)Pb(Mg1/3Nb2/3)O3—(x)PbTiO3 where x=0.2 to 0.5 or the piezoelectric compound (1-y)Pb(Zn1/3Nb2/3)O3—(y)PbTiO3 where y=0 to 0.2 as a substrate with at least one magnetic thin film applied thereto which has grown epitaxially, is disclosed.

Abstract: Current-dependent resistive component, especially one that can be used as a switch, sensor or storage element, a ≦4 nm thick layer of manganate which is provided with electrical contacts and has been applied on a substrate.
