متن کاملCation Distribution in Co0.7Me0.3Fe2O4 (Me = Zn, Ni and Mn)
Co0.7Me0.3Fe2O4 (Me = Zn, Ni and Mn) were synthesized through co-precipitation method. Cationic distribution for these ferrites was proposed on the basis of magnetization measurements and available occupancy of the substituent ions into the spinel lattice. Theoretical lattice constant calculations confirm the proposed cationic distributions were the correct ones.
متن کاملExtraction of Zn, Mn and Co from Zn-Mn-Co-Cd-Ni containing solution using D2EHPA, CYANEX® 272 and CYANEX® 302
Effects of pH, D2EHPA, Cyanex® 302 and Cyanex® 272 on extractions of zinc, manganese and cobalt from a Zn-Mn-Co-Cd-Ni containing solution was comprehensively investigated at the room temperature. The addition of Cyanex® 302 indicated a left-shifting-effect on the extraction curve of zinc, a right-shifting-effect on the extraction curve of manganese and no effect on the extraction of cobalt. The...
متن کاملDilute moment n-type ferromagnetic semiconductor Li(Zn,Mn)As.
We propose to replace Ga in (Ga,Mn)As with Li and Zn as a route to high Curie temperature, carrier mediated ferromagnetism in a dilute moment n-type semiconductor. Superior material characteristics, rendering Li(Zn,Mn)As a realistic candidate for such a system, include high solubility of the isovalent substitutional Mn impurity and carrier concentration controlled independently of Mn doping by ...
متن کاملFerromagnetic behaviour of the Zn–Mn–O system
Polycrystalline Zn–Mn–O samples with nominal manganese concentrations x = 0.01, 0.04 and 0.10 were synthesized by a solid state reaction route using (ZnC2O4·2H2O)1-x and (MnC2O4·2H2O)x. Thermal treatment of the samples was performed in air at temperatures 673, 773, 873, 973 and 1173 K for x = 0.01 and at the temperature 773 K for x = 0.04 and 0.10. The samples were investigated by X-ray diffrac...
