EPR investigations of solid solutions of TSCC and TSCB doped with Mn2+

EPR investigations of Mn²⁺-doped solid solutions of TSCC and TSCB were performed between 4.2 K and 300 K. The Curie temperature vs. molar fraction of bromide x is nonlinear, for x ≧ 0,75 no ferroelectric EPR-line splitting occurs. The relation between the line widths and the molar fraction of bromide is discussed by means of a simple statistical model.
