Nanomagnetism and Spintronics (NanoSpin)

Our research focuses on experimental studies of magnetic, magneto-optical, and spin-transport phenomena in new functional materials and hybrid nanoscale structures.

We work on nanoscale phenomena and materials for future memory and unconventional computing technologies. We are interested in approaches that can be disruptive to the field. We study new control mechanisms of magnetism involving low-power voltages and ultrafast laser pulses. We work on low-loss hybrid magnonics, coupling of magnons to phonons, photons, and plasmons, reconfigurable magnonic neural networks, active control of magnetic skyrmions, and emerging phenomena in artificial spin ice. For smart in-sensor computing, we develop multisensory interconnected networks that can process multimodal information using photomemristor networks with build-in memory.

We are a multidisciplinary and experimental research group. Our laboratory houses dedicated equipment for material growth, lithography, and structural, magnetic, and electronic transport characterization. We operate pulsed laser deposition and magnetron sputtering systems for high-quality film growth, use super-Nyquist sampling magneto-optical Kerr effect microscopy and broadband spin-wave spectroscopy for spin-wave characterization, measure magnetoplasmonic properties using a femtosecond-laser setup and magneto-optical spectrometry, and analyze magnetic properties by various microscopy and magnetometry techniques.
