Magnetic and optical properties of single 4fn and mixed 4fn−15d electronic configurations of trivalent rare earth ions in wide band gap dielectric crystals

The investigation of mechanisms of the magneto-optical activity of rare-earth iron garnet single crystals

“…The electric dipole transition between the 4f 3 and 4f 2 5d configurations may be studied by taking into account the spin-orbit crystal field and superexchange interaction in the development [4,7].…”

“…In recent years, the optical and magneto-optical properties of ferrimagnetic garnets have attracted increasing interest, from the physical or the application points of view. Dispersive MO effects in pure and substituted rare-earth iron garnets have been the subject of numerous experimental and theoretical investigations [1][2][3][4][5][6][7][8][9][10]. To the best of our knowledge, few results concerning the Faraday rotation (FR) in the RIG have been published [2][3][4][5].…”

Emission and Excitation Spectra of Ce3+ and Pr3+ Ions in Hexafluoroelpasolite Lattices

“…With the current availability of synchrotron radiation sources, and the recent theoretical developments for 4f N –1 5d energy level calculations and 4f N –4f N –1 5d transition intensity simulations, new experimental studies and interpretations have been forthcoming, especially for lanthanide ions (Ln 3+ ) doped into wide band gap hosts. − The vacuum ultraviolet (VUV) spectra of Ln 3+ ions doped at the S 4 site of LiYF 4 have received particular attention. − Other interconfigurational studies of the 4f 1 Ce 3+ and 4f 2 Pr 3+ ions have employed the CaF 2 − and KMgF 3 , hosts. The 4f 1 –5d 1 absorption transition of Ce 3+ is electric dipole allowed and comprises up to five bands in the ultraviolet spectral region, corresponding to transitions to the Kramers doublet levels derived from E g and T 2g orbitals of the 2 D multiplet.…”

The magneto-optical activity of rare-earth ion in Y-substituted erbium and neodymium iron garnets

“…The electric dipole transition between the 4f 3 and 4f 2 5d configuration split states are studied taking into account the spin-orbit crystal field and superexchange interaction in developing [7,11].…”

“…Dispersive MO effects in pure and substituted rare-earth iron garnets (RIG) have been the subject of numerous experimental and theoretical investigations [1][2][3][4][5][6][7][8][9][10][11][12]. To the best of our knowledge, despite the abundant literature, few results concerning the FR in the RIG have been published [5][6][7][8].…”
