Crystals possessing natural optical activity and belonging to point groups C n or C nv ( ) provide an example, where helicity is preserved along the principal axis [ 42 ] while the duality symmetry is broken.
WebJul 1, 1996 · A microscopic model of nonreciprocal optical effects in antiferromagnets is developed by considering the case of ${\\mathrm{Cr}}_{2}$${\\mathrm{O}}_{3}$ where such effects have been observed. These effects are due to a direct coupling between light and the antiferromagnetic order parameter. This coupling is mediated by the spin-orbit interaction … Webserial bideposition has led to a normal-columnar nanostructure with enhanced birefringence and in turn ...
