“…Normal spinel-type chromium sulfides MCr S and partially inverse spinel-type indium sulfides MIn S (M"Mn, Fe, Co, and Ni) display complete mutual solid solubility at elevated temperatures (1)(2)(3)(4)(5)(6). These solid solutions show spin glass behavior at low temperatures.…”

“…These solid solutions show spin glass behavior at low temperatures. They decompose at temperatures below 1050-1300 K (depending on M) to chromium-rich and indium-rich spinel-type solid solutions (5)(6)(7)(8). The sections with constant M'' content deviate more or less from quasibinary behavior.…”

“…1981;Lutz et al, 1983;Lutz et al, 1986). These solid solutions decompose into Cr-rich and In-rich spinel-type mixed crystals at temperatures below 1075°Κ for Mn, 1125° Κ for Fe and 1275° Κ for Co (Lutz et al, 1983;Lutz et al, 1986). The Cr-rich phases form normal spinels and the In-rich inverse spinels (Hill et al, 1979).…”

The structure and site-occupancy of the spinel-type MnCrInS 4 was determined from powder diffraction data using synchrotron radiation (A = 0.748 Ä) and the two-step method (integrated intensities determined by individual profile fittings followed by last-squares refinement). A Rietveld analysis was also done in order to check for the reliability of the method. The site-occupancy formula was [Mn 0 75 Ιη 0 .25] [Cr 0 . 5 Mn 0 .i2-Ι η 0.38]2$4.

Raman Single Crystal Studies of Spinel TypeMCr2S4(M=Mn, Fe, Co, Zn, Cd), MIn2S4(M = Mn, Fe, Co, Ni), MnCr2 -2xIn2xs4 and Col -,CdxCr2S4" The Raman spectra of single crystals (grown by chemical vapour transport with I,, AICI,, CrCI, and InCI, as transporting agents) and polycrystalline samples of spinel type MCr,S, (M = Mn, Fe, Co, Zn, Cd), MIn,S, (M = Mn, Fe, Co, Ni), MnCr,-,,In,S, and Co,-,Cd,Cr,S, were recorded. The main results obtained are (i) large resonance enhancement effects, (ii) breakdown of the translation symmetry in inverse spinels (MIn,S,), which results in band broadening and the observation of more bands than group theoretically allowed, e.g. a clustering mode ( A in both spinel solid solutions and partly inverse ternary spinels and (iv) frequency shifts of the observed bands caused by the tetrahedrally coordinated metal ions due to mass effects (F,# modes) and both bonding (ionic charge, covalency) and repulsion interactions ( A at about 250 cm-', (ii) two-mode behaviour of the breathing modes of the tetrahedral MS, units ( A modes).
