A combined study of phase transitions in the La0.9Sr0.1MnO3 compound was ca
rried out using X-ray, electrical, and magnetic techniques. Two structural
phase transitions were revealed at temperatures of ranges 100-115 K and 300
-340 K. At temperatures 100-115 K, the transition proceeds with changing in
the magnetic state of the compound, namely, in saturation magnetization an
d contribution of the paraprocess to the sample magnetization. (C) 1999 Els
