Abstract

We present an extensive study of the electric, magnetic and elastic responses\nof tetragonal ferroelectrics under illumination, using a new theory\nintertwining material and wave symmetries. Optical rectification,\nphotomagnetic, photovoltaic and phototoroidal vector responses are worked out\nas functions of the wave vector and wave polarization directions. Second-order\nresponse tensors associated with photoelastic, photomagnetoelectric,\nphotorefractive effects and photoconductivity are described. We discuss in\ndetail the photo-Hall and a new non-linear optical effect in tungsten bronzes.\nFinally, we compare the properties of tetragonal materials with those of\nhexagonal, orthorhombic and trigonal ferroelectrics previously reported in the\nliterature.\n
