Research Areas:

Multiferroic magnetoelectric composites are gaining interest for their applications in sensors, signal filters, phase shifters, high frequency devices and memory devices. In magnetoelectric composites, a piezoelectric (PE) material is paired with a magnetostrictive (MS) material. Thus when the composite is exposed to a magnetic field, the magnetostrictive material will expand causing the piezoelectric material to generate a charge and this is known as the magnetoelectric effect. Magnetoelectric composites depend on the selection of the material for the PE and MS phase and depends on the geometries materials relative to each other. Currently, Nickel Ferrite is the MS phase and  Lead Zirconate Titanate (PZT) is the PE phase. My research is to alter the geometry of the MS and PE layers through nanoimprint lithography (NIL) and investigate its effect on the magnetoelectric response and the diffusion between the MS and PE layers.
