The evolution during thermal treatment of the precursor obtained by a new method to synthezise barium hexaferrite by chemical coprecipitation is described; the method involves the precipitation froma strongly alkaline ferrate(V1) solution containing barium chloride. Barium hexaferrite may be formed by heating of the original superparamagnetic precursor at temperatures as low as 700QC as shown b...

The effects of stoichiometry factor on the magnetic and structural properties of perpendicular barium ferrite thin films with composition of BaO (Fe2O3) were systematically investigated. Within the range 2 2 6, the -axis for barium ferrite thin films can be oriented perpendicularly by the use of Pt underlayer and with optimized processing conditions. Perpendicular -axis orientation becomes wors...

BACKGROUND/AIMS A colon transit time test using radio-opaque markers (CTTRM) is considered the gold standard for evaluating colon transit function. A 24-hour delayed film of barium enema (BE) has been used as a supplementary method in structural evaluations. The aim of this study was to evaluate the utility of a 24-hour delayed BE film for assessing colon transit function in young children with...

Synthesis of BaFe12O19 magnetic nano particles via precipitation in different pH conditions have been reported. The certain molar ratio of Fe/Ba = 12 selected and sodium hydroxide was used as a precipitant agent. X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and vibrating sample magnetometer (VSM) were used to consider the structural, morphological and magnetic properties of bariu...
