SPIN INSULATRONICS

Overview

Microwave oscillations of the magnetization around its equilibrium are the natural dynamical response to external perturbations (e.g. thermal fluctuations, microwave fields). This offers the promise for a new class of microwave devices, benefiting from their small foot-print, their ability to be controlled electrically, and their integrability with CMOS technology. Identified devices include local oscillators, microwave filters, detectors, and non-reciprocal devices. Understanding the dynamics of these nano-objects, applying general concepts of microwave oscillator techniques and defining from this novel microwave applications is the major aim of this activity.

Research directions

Magnonics

Magnons are the quasi-particles associated to the collective excitations of spins. Mode engineering and transfer of angular momentum by magnonics current are some of our key ongoing research activities.
