Terahertz-Light Driven Coupling of Antiferromagnetic Spins to Lattice

Abstract

Understanding spin-lattice coupling represents a key challenge in modern condensed matter physics, with crucial importance and implications for ultrafast and 2D-magnetism. The efficiency of angular momentum and energy transfer between spins and the lattice imposes fundamental speed limits on the ability to control spins in spintronics, magnonics and magnetic data storage. We report on an efficient nonlinear mechanism of spin-lattice coupling driven by THz light pulses. A nearly single-cycle THz pulse resonantly interacts with a coherent magnonic state in the antiferromagnet CoF2 and excites the Raman-active THz phonon. The results reveal the unique functionality of antiferromagnets allowing ultrafast spin-lattice coupling using light.
