“…Based on the literature review, the I-II 2 -III-VI 4 family (I = Cu, Ag; II = Zn, Cd; III = Ga, In; and VI = S, Se) compounds are reported to have a tetragonal structure, close to the parent chalcopyrite structure. [7][8][9][10][11] Delgado et al (2008) determined that CuFe 2 InSe 4 crystallizes in the tetragonal stannite structure, space group I% 42m. 9 Chen et al 12 have calculated the stability of several crystal phases from a cation cross-substitution perspective and found that the stannite structure generally has a higher energy than the kesterite structure after relaxation.…”

“…The present work, where we have studied the solid solubility of VSe in AgInSe 2 in the composition range of interest, i.e. 0 ≤ x ≤ 0.5, is a part of a systematic study on (I-III-VI 2 )-(TM-VI) alloys [6][7][8][9].…”

. Fn, 64.70.Kb, 81.70.Pg Polycrystalline samples of the (AgInSe 2 ) 1-x (VSe) x system were prepared by the melt and anneal method. The anneal temperature was 900 K and the anneal time one month. The step composition was 0.1 and the weight of each sample approximately 1 g. Additionally, the composition x = 1/3 was also prepared, since these alloys have been reported as electronic, i.e. definite compounds exist in the diagram at precise values of composition, one of them x = 1/3. The stoichiometric relation of the samples was investigated by SEM technique. The experimental values, in average, are very close to the nominal values, all of them lying inside the interval of the experimental error (± 5%). X-Ray Diffraction (XRD) and Differential Thermal Analysis (DTA) techniques were used for characterization of the alloy samples. Guinier photographs were obtained for all the samples and unit cell parameters were calculated using the available software for indexation. The diffraction patterns show sharp lines indicating good thermal equilibrium of the samples. Transition temperatures obtained from DTA measurements were manually obtained from the ∆T vs. T graph with the criteria that the transition occurs at the intersection of the base line with the slope of the thermal transition peak, as usually. From the analysis of the experimental results it was observed that the solid solubility of VSe in AgInSe 2 is approximately 20%, i.e. the single-phase region exists in the composition range 0 ≤ x < 0.2, whereas for x > 0.2 at least two phases coexist. A schematic T-x phase diagram is proposed.1 Introduction It is expected that chalcopyrite-based diluted magnetic semiconductors (ChDMSs) having room temperature ferromagnetism could have a deep impact on the industrial applications [1,2]. These quaternary materials were obtained alloying ternary chalcopyrites I-III-VI 2 or II-IV-V 2 with Transition Metals (TM) as Ti, V, Cr, Mn, Fe, Co and Ni. Recently, theoretical studies with Mn as TM have been done in order to clarify the relation between the predicted ferromagnetic tendencies and the site preference for Mn [3,4].

Scandium, yttrium and the lanthanidesLaser-ablated scandium atoms react with H 2 O/N 2 mixtures to give matrix-trapped (Z 1 -N 2 )Sc(H)OH, (Z 1 -N 2 ) 2 Sc(H)OH and (Z 2 -N 2 )Sc(H)OH. nScH assignments, based on isotopic shifts and DFT calculations, are listed in Table 1. 1 The FTIR spectrum of Sc 3 N@C 80 gave assignments for two isomers-both with trigonal planar Sc 3 N units. 2 There is IR evidence that ScO + in noble gas matrices forms adducts [ScO(Ng) 5Àn (Ng 0 ) n ] + , where n = 0-5, Ng, Ng 0 = Ar, Kr, Xe. nScO assignments are given in Table 2. 3 Laser-evaporated ScO and N 2 , or Sc atoms and N 2 O form the matrix-trapped species OSc(Z 2 -N 2 ). This rearranges to an Z 1 -form (OScNN) on UV irradiation. nScO for the former is at 906.5 cm À1 , and for the latter at 894.6 cm À1 . 4 The Raman spectrum of [Sc(OSMe 2 ) 6 ] 3+ includes symmetric (a g ) and degenerate (e g ) nScO modes at 429, 451 cm À1 , respectively. The IR spectrum includes bands at 452 and 463 cm À1 due to e u , a u modes, respectively. 5 Ab initio calculations gave skeletal vibrational wavenumbers for Sc(mda) 3 ,where mda = C 3 H 3 O 2 À . 6 Raman studies have revealed grain-size effects for nanocrystalline ZrO 2 -Sc 2 O 3 , i.e. (ZrO 2 ) 1Àx (Sc 2 O 3 ) x , where x = 0.02-0.16. 7 The IR and Raman spectra of M 2 (M 0 O 4 ) 3 , where M = Sc, In, M 0 = Mo, W, gave characteristic assignments. For Sc 2 (MoO 4 ) 3 , variable-temperature spectra show the effects of the ferroelastic phase transition. 8 There have been two other reports of Raman studies of the phase behaviour of Sc 2 (MoO 4 ) 3 . 9,10 Raman spectroscopy was used to characterise intermediate compositions in the systems Ln 2 S 3 -Ln 0 2 S 3 , where Ln = La, Dy, L 0 = Sc, Lu etc. 11 The variable-temperature Raman spectra of Rb 2 KScF 6 (elpasolite) were used to follow temperature-induced phase transitions (using both ScF 6 and lattice modes). 12 The IR spectra of MCl 2 (k 3 -L)(thf), where M = Sc, Y, HL = (1), R = COOH, CSSH and CH 2 OH, include nMS near 300 cm À1 , and nMO (R = CH 2 OH) 570 cm À1 . 13 Characteristic Raman bands were seen at 204 and 42 cm À1 for a superconducting YNi 2 B 2 C single crystal. 14 The IR spectrum of Y 2 O 3 shows that nY-O shifts to lower wavenumber with decreased particle size. 15 Variable-temperature Raman spectroscopy was used to follow phase transitions of Y 2 O 3 -ZrO 2 . 16 IR and Raman spectra gave vibrational wavenumbers for orthorhombic M 2 BaCuO 5 , where M = Y, Ho or Gd, assigned using a short-range force constant model. 17 The Raman spectra of Ln 3 NbO 7 , where Ln = Y, La, Nd, Gd, in the temperature range 298-973K gave evidence for reversible structural disordering on increasing temperature. 18 IR data, together with previous Raman bands, gave assignments for KY 3 F 10 single crystals, supported by a normal coordinate analysis. 19 The IR and Raman spectra of [Ln(OH 2 ) 9 ] 3+ , where Ln = La, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb or Lu, gave detailed assignments for the LnO 9 unit (D 3h ). 20 Structural characteristics of MFeGe 2 O 7 , where M...
