with regard to dicyan-diamide. 6) The X-ray analysis was also
successfully used in the examination of luminophores, and can
also-be applied for the examination of other substances (e.g.
catalysts).

~the Curie temperature decreases in PbTiO Lareo when the LaFeO

different polarizability of'the La and Bi ions compared with the
polarizability of the Pb 'ion.. The different ionic radii of Bi (1.20 1) and
La (1-04 1) probably do not influence the behavior of the Curie temperature.
Presumably they are the main reason~of the different sequence of the
phases'. The jelatively high temperature of the magnetic transformation of
LaFeO (_ 570 C) in part of the solid solutions in its neighborhood also
