Magnetic and Fluorescence Properties of Cerium-doped Yttrium Aluminum Iron Garnet Nanocrystals

Electron-phonon coupling in iron-doped yttrium aluminum garnet

The electron-phonon coupling in iron-doped yttrium aluminum garnet crystals is studied in the theoretical framework of linear and quadratic coupling. The line shift and line broadening of the zero phonon line of iron centers as a function of temperature between 10 and 150 K is qualitatively and quantitatively explained. The spectroscopic features of the line, deduced from the theory of lattice ...

Three-photon absorption in Nd-doped yttrium aluminum garnet

This paper presents the results of a study of resonantly enhanced, three-, photon absorption in Nd-doped yttrium aluminum garnet (Y3Alg0~2) or Nd: YAG. The trivalent ions of the rare-earth elements, such as Nd'+, are characterized by energy levels which remain relatively sharp even in a crystalline environment, and thus crystalline solids doped with rare-earth ions present interesting systems i...

Magnetic Anisotropy and Phase Transitions in Co-Doped Yttrium Iron Garnet Films

YIG:Co,Ca,Ge films grown on (001) plane substrate were investigated down to liquid helium temperatures using torque anisometry technique. Successively lowering temperature spin-reorientational transitions were observed between following easy magnetization axes (EMA) orientations: (i) at room temperature four EMA inclined to the film plane from [I 111 directions; (ii) two EMA near the [I101 and ...

Yttrium Aluminum Garnet Fibers from Metalloorganic Precursors

Mixtures of yttrium acetate hydrate (Y(O2CCH3)3?4H2O) and aluminum formate hydrate (Al(O2CH)3?3H2O in H2O) or yttrium isobutyrate (Y[O2CCH(CH3)2]3) and aluminum isobutyrate (Al[O2CCH(CH3)2]3) in tetrahydrofuran were used as precursors to process yttrium aluminum garnet (YAG, Al5Y3O12) fibers. The pyrolytic decomposition patterns of Al(O2CH)3?3H2O, Y(O2CCH3)3?4H2O, and a [3Y(O2CCH3)3?4H2O/5Al(O2...
