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.
Nanomagnetism and Spintronics (NanoSpin)
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.

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.
