摘要
The interference of the time-invariant magnetic-dipole contribution with the time-noninvariant electric-dipole contribution to the second harmonic (SH) provides a mechanism which is sensitive to the reduction of symmetry of Cr2O3 by antiferromagnetic ordering of spins. A pronounced polarization dependence of the SH on the sign of the order parameter is observed in the 1.7-3.1 eV spectral range. The effect is used to study the domain structure of Cr2O3 by use of a CCD camera. Exposure times in the order of minutes are sufficient to yield a high-resolution image of domains in samples of 10 mm2.© 1995 American Institute of Physics.
