“…Quantum theory of FR used by us in this work allows us to be confirm in the conclusion, made in [12], concerning the nature of MO activity of Er 3+ ion in Y-substituted erbium iron garnets. The validity of the single-ion model of Er sublattice contribution to a non-resonant FR shows that we can consider the rare-earth and iron sublattices to the overall rotation within the "transparency range" independently.…”

“…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].…”

“…Nd 3+ ion has large radius and "readily" substitutes Y ion in dodecahedral positions in crystals; Nd 3+ concentration in RIG with the formula Nd x Y 3−x Fe 5 O 12 cannot exceed 2.0 [9]. It has been shown [12] that the superexchange interaction influences on the mixing of wave functions in the ErO 8 13− molecule. The examination of MO properties of Er x Y 3−x Fe 5 O 12 (x = 0.4, 1.0, 1.5, 2.5 and 3.0) have been presented in this work; in addition to the result [12], two more samples (x = 1.0 and 3.0) and Nd x Y 3−x Fe 5 O 12 (x = 0.5, 0.96, 1.39 and 1.72) single crystals have been studied in energy regions of 5500-13,000 cm −1 and 6000-17,000 cm −1 respectively.…”

The magnetic and magneto-optical properties of the typical representatives of three rare-earth iron garnets (RIG) groups: with heavy rare-earth elements Yb, Er, Dy, Tb; with elements from the middle of lanthanide series Gd, Sm, and with light rare-earth element Nd are presented. In contradistinction to other work on the Faraday rotation, which were done only at 1152 nm (8696 cm −1 ), here we present FR spectra obtained in the energy region 5500-20000 cm −1 with high optical resolution. The investigations have been done at temperatures of 5, 82, 130, 295 K using magnetic field up to 25 kOe applied parallel to the [111] crystallographic axis of the crystals. It has been shown that the contribution proportional to the magnetic field and independent of temperature to the mixing of the ground state multiplets exceeds the paramagnetic contribution in YbIG, ErIG, GdIG, SmIG. In Tb and Dy iron garnets contributions from the two mechanisms have opposite signs, and the paramagnetic mechanism gives the greatest contribution to the Faraday rotation. Nevertheless, the contribution of the diamagnetic mechanism, caused by the influence of the exchange field in the iron sublattices on rare-earth ions, is significant, and it is necessary to take it into account. Anomalously large magneto-optical activity is observed in NdYIG. This is the result of contributions of the same sign and approximately equal in magnitude from the paramagnetic and diamagnetic mechanisms.

“…Most of the previous studies have concentrated on the preparation of Biand Ce-doped YIG powders and films because of their high Faraday rotation coefficient [10][11][12][13][14][15][16][17]. Some studies have been carried out on Er-YIG powder nanoparticles [18][19][20][21][22][23][24][25][26][27].…”

Nanoparticles Y 3−x Er x Fe 5 O 12 (x = 0.2, 1.0, and 2.0) thin films were prepared by sol-gel method and treated at 800, 900, and 1000• C, respectively, for 2 h. The films have single phase garnet structure and the sizes of particles are in the range of 44 to 83 nm. The magnetic measurements show that the saturation magnetization decreased with increasing of Er concentration for all samples treated at different annealing temperatures. The saturation magnetization increased with the particle size due to the enhancement of the surface spin effect. The coercivity initially decreased for x = 1.0 and then increased for x = 2.0 with increasing annealing temperature.
