"Detection of Antiferromagnetic Domains by Optical Magnetoelectric Effect"

Kivonat: "One of the main motivation behind the current interest in 
magnetoelectric materials is that they can be building blocks of low-energy 
consumption nonvolatile memory devices. In this talk, I will demonstrate that 
simple optical absorption spectroscopy can be used to identify 
magnetoelectric (ME) antiferromagnetic (AFM) domains of LiCoPO4. In case of 
the THz spin-wave excitations this unusual contrast arising from the optical 
magnetoelectric effect as confirmed by our microscopic model, which also 
captures the characteristics of the observed static ME effect. Since these 
domains and the absorption difference are also present in zero magnetic field 
it may promote the development of ME memory devices based on AFM insulators."
