The Effect of Zn- Cr Substitution on the Structural and Magnetic Properties of Cobalt Ferrite Nanoparticles
In this investigation, the structural and magnetic properties of Cr and Zn substituted Co ferrite with the general formula Co1-xZnxFe2-xCrxO4 (x= 0.1, 0.3, 0.5, 0.7) as prepared by sol- gel method were studied. The structural, morphological and magnetic properties of the samples were characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), Scanning electron microscopy (SEM)...
متن کاملInvestigation of Tribological Behavior of Electrodeposited Cr, Co-Cr and Co-Cr/TiO2 Nano-Composite Coatings
Electrodeposition is a simple and economic technique for precision coating of different shaped substrates with pure metal, alloy or composite films. Dc electrodeposition was used to produce Cr, Co-Cr and Co-Cr/TiO2 nano-composite coatings from Cr(III) based electrolytes onto 316L SS substrates. The effects of TiO2 nanoparticles concentration on co-deposition of these particles along with Cr con...

~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...

امروزه لباس در نظر ورزشکاران و کسانی که برای اوقات فراغت خود و یا برای رسیدن به اندامی متعادل، ورزش می کنند؛ بسیار با اهمیت است. احساس مطلوب از لباس در زمره خصوصیات راحتی پوشش می باشد. خصوصیات انتقال رطوبت لباس، در ارزیابی راحتی حسی و حرارتی منسوجات تولید شده از آن ها بسیار مهم است. هدف از این تحقیق، معرفی پارچه جدید است که متشکل از الیاف استبرق با خواص منحصر به فرد می باشد. استبرق لیف طبیعی تو...
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...
