| الوصف: | The concept of charge-transfer (CT) transitions in ferrites is based on the cluster approach and takes into account the relevant interactions as the low-symmetry crystal field, spin-orbital, Zeeman, exchange and exchange-relativistic interactions. For all its simplicity, this concept yield a reliable qualitative and quantitative microscopic explanation of spectral, concentration, temperature, and field dependences of optic and magneto-optic properties ranging from the isotropic absorption as well as the optic anisotropy to the circular magneto-optics. In this review paper, starting with a critical analysis of the fundamental shortcomings of the "first-principles" DFT-based band theory we present the main ideas and techniques of the cluster theory of the CT transitions to be main contributors to circular magneto-optics of ferrites.
