Magnetic properties of KRE(WO4)2 (RE=Gd, Yb, Tm) single crystals

EPR and optical properties of KYb(WO4)2 and KTb0.2Yb0.8(WO4)2 single crystals

“…9 0.5 K for the former and latter crystals, respectively. The features agree well with ones derived by Borowiec et al [1]. …”

“…The Electron Paramagnetic Resonance (EPR) technique is very useful for the determination of both the site symmetry and kind of magnetic interaction in crystals and powders. Using this technique, Yb 3+ ions doped in KY(WO 4 ) 2 were previously investigated by Prokhorov et al [5], whereas the dense magnetic system in a KYb(WO 4 ) 2 single crystal was analyzed by Pujol et al [6] and recently by Borowiec et al [1]. In the present work, we have examined a KYb(WO 4 ) 2 single crystal obtained by the method described by Borisov, Klevtsova [7].…”

“…They determine the variety of magnetic, electronic, and crystallographic structures in such systems [1,2]. The luminescence properties of rare earth (RE) double tungstates are closely connected with 4f-4f transitions and may be con- * presented at the 3rd International Workshop on Advanced Spectroscopy and Optical Materials, July 17-22, 2011, Gdańsk, Poland † E-mail: skaczmarek@zut.edu.pl trolled by tuning the chemical and physical interactions.…”

Magnetic Properties of the RbNd(WO4)2Single Crystal

“…At present, the AReW tungstates having the low-symmetric (e.g., monoclinic) crystalline structure and the atom arrangements in forms of chains or layers are intensively studied. Structural, optical, and magnetic investigations of the KDyW, KHoW, KErW, KGdW, KYbW, KTmW and RbDyW compounds were performed earlier [1,[4][5][6][7][8]. Many of them show complicated structural phase transitions (SPT), caused by the cooperative Jahn-Teller effect (CJTE), and magnetic phase transitions.…”

“…Many of them show complicated structural phase transitions (SPT), caused by the cooperative Jahn-Teller effect (CJTE), and magnetic phase transitions. Unlike the high symmetry crystals, they are characterized by strong magnetic anisotropy, low local symmetry and low-dimensional magnetic structure, and they exhibit strong spin-lattice coupling [1,[8][9][10]. The rubidium neodymium double tungstate was also studied, especially its structural and spectroscopic properties [1][2][3].…”
