The new, ferromagnetic perovskite type oxide LaMn1/2Rh1/2O3 has been synthesized by conventional ceramic techniques. Rietveld refinements from X-ray diffraction data confirm a slight GdFeO3-type distortion and a disordered cation arrangement on the B

New perovskite type oxides of Rh(IV) (La2MRhO6; M = Mg, Zn) have been prepared by conventional techniques used in solid state chemistry. Rietveld refinements from X-ray diffraction data confirm the space group P21/n for both compounds. This low symme

A magnetic susceptibility and Mossbauer spectroscopy study of the perovskite Bi 2 FeRhO 6 was undertaken. A freezing start temperature around 270 K was evidenced by both methods, Unlike homogeneous magnetic systems the freezing occurs by involving co

The catalytic activity under selective catalytic reduction conditions for composites between the spinels MgAl2O4 or ZnAl2O4 and CuO are reported. It is shown that the conversion of NO into N2 starts at about 250°C and reaches a maximum value of abou

The crystal structure of both Bi 0.5 Sr 1.5 YCu 1.5 Fe 0.5 O 6 and Sr 2 Pb 0.5 Y 0.5 CuFeO 6 is basically composed of double layers of (Cu,Fe)O 5 pyramids. In order to better understand the magnetic properties of this type of compound, a 57 Fe Mossba

A series of cuprates of type Bi-0212 has been prepared. The crystal structure was refined from neutron powder diffraction data at room temperature and 10 K as tetragonal (space group I4/mmm). Mossbauer and susceptibility measurements of the Fe substi

In the system Bi-0212 the carrier concentration can be changed by both cation substitution and oxygen content. The crystal structure of Ca substituted material was refined from neutron powder diffraction data for Bi0.5Sr1.5Ca0.5Y0.5Cu1.5Fe0.5Oy. It i
