Resonant optical control of the structural distortions that drive ultrafast demagnetization in Cr${}_2$O${}_3$

Vera G. Sala, Stefano Dal Conte, Timothy A. Miller +5

We study how the color and polarization of ultrashort pulses of visible light can be used to control the demagnetization processes of the antiferromagnetic insulator Cr${}_2$O${}_3$. W…
