Mossbauer Spectroscopy and Crystal Chemistry of Aenigmatites
VIII VI IV Aenigmatite, Na4 (Fe2 +,Ti,Fe 3 +) 1 2 (SiFe 3 +) 12 0 40 , is a common constituent of sodium-rich alkaline igneous rocks and is classified as an open-branched single-chain silicate, whose structure is closely related to that of sapphirine. The first Mossbauer spectra of three valid aenigmatite specimens were recorded and the detailed crystal chemistry were obtained. In the Mossbauer...
متن کاملMOSSBAUER SPECTROSCOPY OF MAGNETIC PHASES IN FeCl
~ong the easy axis a at 4.2 K induces phase transi tionsatHI =39 kOe andH2 =46 kOe [1-3]. In this ~t1er we report the use of Mossbauer spectroscopy in external magnetic fields to study the magnetic struc (ure of each of the three phases. Previous Mossbauer work in FeCI2 · 2HZ0 includes apower study by Chandra and Hoy [4] and a single z crystal study by Johnson [5]. They found a magnetic o hyp...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولMossbauer Spectroscopy of 57 Fe Dennis
Using recoilless Mossbauer spectroscopy methods, we investigate the atomic absorption spectra of the 14.4keV transition in Fe compounds. The natural linewidth of this transition is determined to the correct order of magnitude with χν = .75. Hyperfine energy shifts in iron oxide and iron sulfate are investigated and measured. The ratio of ground and excited state magnetic moment in Fe is found t...
متن کاملEmergency Location Problems with an M/G/k Queueing System
Since late 1960's, the emergency location problems, fire stations and medical emergency services have attracted the attention of researchers. Mathematical models, both deterministic and probabilistic, have been proposed and applied to find suitable locations for such facilities in many urban and rural areas. Here, we review some models proposed for finding the location of such facilities, wit...
