Our Research

Our group works on new nanoscale phenomena and materials for future memory and analogue computing technologies. In particular, we are interested in approaches that can be disruptive to the field. We study new control mechanisms of magnetism involving low-power electric fields and ultrafast light pulses. We also are working towards deterministic manipulation of spin waves, transport and switching of topological skyrmions, and frustration by design in artificial spin ice lattices. For cognitive computing, we develop new electronic and optoelectronic materials that emulate biological synapses and neurons.

We are a multidisciplinary and experimental research group. Our laboratory houses dedicated equipment for material growth, lithography, and structural, magnetic, and electronic transport characterization. As a frontier technique, we operate an in-situ transmission electron microscopy measurement platform for atomic-resolution imaging under varying irradiation, heating, electric-field, and straining conditions.

E-Field Control of Magnetism

Leveraging strain transfer in multiferroic heterostructures or reversible ion migration in metal/oxide bilayers and complex oxides we seek to control magnetism by low-power voltage pulses in thin magnetic films and nanostructures.

Department of Applied Physics


Using ferromagnetic/ferroelectric bilayers and patterned yttrium iron garnet films we investigate new mechanisms for short-wavelength spin-wave excitation and active spin-wave manipulation.

Magnetic Skyrmions

We investigate the formation, annihilation, switching, and controlled motion of magnetic skyrmions in ultrathin perpendicularly magnetized heterostructures using electric fields.

By design of plasmonic excitations in ferromagnetic metamaterials we tailor their magneto-optical response.

Artifcial Spin Ice

Utilizing frustration by design in 2D and 3D lattices of single-domain Ising-type nanomagnets we explore the real-time dynamics of magnetic excitations in artificial spin ice systems.

Cognitive Computing

Using a variety of memristive electronic and optoelectronic oxide elements we emulate the functions of synapses and neurons in the brain.

In-Situ TEM

Leveraging special specimen holders and a double Cs-corrected transmission electron microscope (TEM) we are imaging nanomaterials under varying electrical biasing and heating conditions.
