The magnetic properties of hexaureatitanium(III) and vanadium(III) salts at very low temperatures

Abstract

The magnetic susceptibility of the perchlorate and iodide salts of the hexaureatitanium(III) and hexaureavanadium(III) cations have been measured to temperatures as low as 4 K in the former and 1.5 K in the latter cases. The results were interpreted to deduce the three parameters of the simplest theory for the splitting of the ground T term for each ion. The parameter sets agree only fairly well with results from the magnetic susceptibility and anisotropy data at higher temperatures.
