Popis: Experiments show that in PrCl 3 , PrBr 3 , and PrES the electric dipole moments of the Pr non-Kramers ground doublets are much larger than the magnetic dipole moments. One-dimensional XY antiferroelectric ordering is observed at low temperatures, and PrCl 3 and PrBr 3 undergo structural phase transitions near 0.4 K.
