✦ Synopsis

A series of perovskite-type complex oxides of general formula La 1.33 Na x Mn x Ti 2-x O 6 (x = 0.66, 0.55 and 0.44) have been obtained and characterised. Magnetic susceptibility measurements on these phases follow a Curie-Weiss-like dependence at high temperatures, although a more complex variation is observed at lower temperatures. The thermal variation of M/H from zero-field-cooled and field-cooled susceptibility measurements shows irreversible processes and magnetisation isotherms that differ from typical ferromag- [a

## Abstract The Behaviour Style Observation System for Young Children (BSOS) was used to predict preschool‐aged children's externalizing and internalizing behaviour problems in middle childhood, 3–5 years after the initial assessment. This observational measurement tool was designed to sample and a

Comprehensive investigations into crystal structures, electrical and magnetic properties of the (Lal-,Ca,)MnO, (z = 0 f 0.6) solid solutions are performed. Two concentration magnetic phase transitions are found : antiferromagnetic-ferromagnetic with x = 0.14 and ferromagnetic (T, = 150 K)ferromagnet
