Magnetic propertiesSpectroscopyThermal analysisGreen singleヽrystals of the hydroxochromate(III) CaNa[Cr(OH)6] were grown under highly alkaline hydrothermal conditions at about 200 °C. The starting materials Ca(NO3)2·6H2O and Cr(NO3)3·9H2O were reacted in a mixture of water and sodium ...
Below T = 6 K, hysteresis loops taken at different temperatures show that Cr[(H3N−(CH2)2−PO3)(Cl)(H2O)] behaves as a weak ferromagnet with the critical temperature TN at 5.5 K. The spin canting is responsible of the long-range magnetic ordering. The values of the coercive fie...
Mssbauer spectra were measured at room temperature for the compounds Fe2(C2O4)3·6H3O, Ba3[Fe(C2O4)3] 2·8H2O, and Sr3[Fe(C2O4)3] 2·2H2O. Values of the isomer shift relative to Cu(Co57) are +0.15, +0.03, and +0.16 mm./sec. and the quadr... PK Gallagher,CR Kurkjian...
Fig. 6. Magnetic structure of La0.3Ca0.7Fe0.7Cr0.3O3-δ at RT. At RT, an average magnetic moment of 1.52(3) μB for Fe and Cr cations was determined, while the calculated magnetic moment would result in μ = (0.7x5μB-0.3x3μB) = 2.5 μB, which is higher than the...
Reaction of (NBzEt3)2[VOCl4] (1a) with NaO2CPh and atmospheric H2O/O2 in MeCN leads to formation of (NBzEt3)2[V5O9Cl(O2CPh)4] 4a; a similar reaction employing (NEt4)2[VOCl4] (1b) gives (NEt4)2[V5O9Cl(O2CPh)4] (4b). Complex 4a·MeCN crystallizes in space group P212121...
