Toroidal vortices are whirling disturbances rotating about a ring-shaped core while advancing in the direction normal to ring orifice. commonly found nature and being studied wide range of disciplines. Here we report experimental observation photonic toroidal vortex as new solution Maxwell's equations with use conformal mapping. The helical phase twists around closed loop leading an azimuthal l...

In this paper we present an analysis of the magnetic toroidal moment and its relation to the various structural modes in R3c-distorted perovskites with magnetic cations on either the perovskite A or B site. We evaluate the toroidal moment in the limit of localized magnetic moments and show that the full magnetic symmetry can be taken into account by considering small induced magnetic moments on...
