%T Switchable Voltage Control of the Magnetic Anisotropy in Heterostructured Nanocomposites of CoFe/NiFe/PZT
%X In this work, we study the magnetic properties of a CoFe/NiFe/PZT heterostructured nanocomposite
that is affected by the strain in the PZT substrate when a voltage in the range from –250
to 250 V is applied. An interesting electric-voltage-controlled magnetic anisotropy, with a relative
increase in magnetization up to above 100%, is observed. This brings a new challenge to operate a
low-power-consuming spin electronic device. We also utilize a theoretical model based on interfacecharge-
mediated and strain-mediated magnetic-electric coupling to understand the change in the
magnetic properties of the investigated material.
