Abstract

A coexistence of electric and magnetic order in hexagonal YMnO₃ gives rise to an unusual nonlinear optical polarization P(2(omega) ) which contains two contributions defined by the two order parameters. The two contributions overlap over a wide frequency range thus opening up new possibilities to study the electronic structure of crystals. The magnitude and phase of P(2(omega) ) can be changed by varying the ratio between the two contributions. We show that 180 degree ferroelectric and antiferromagnetic domains, which are indistinguishable in linear optics, can be visualized with a high contrast using the second harmonic light.
