the thermal expansion Dl/l are studied on La1-xSrxMnO3 single crystals with x=0.1, 0.15, and 0.3. For
the conducting sample with x=0.3 and the semiconducting sample with x=0.15 the volume magnetostriction (w=l||+2l^) is negative and the |w|(T) curves go through a maximum at the Curie point TC. At T > TC its Dl/l temperature dependence is stronger than the linear one. For the semiconducting sample with x=0.1 w is negative at T < TC and |w|╝0 at T~TC. Its Dl/l is linear at T ≥ TC. The behavior of w and Dl/l are explained by a magnetic two-phase state, due to strong s-d exchange.}, number={4}, journal={ФІЗИКА НИЗЬКИХ ТЕМПЕРАТУР}, author={Koroleva, L. I. and Abramovich, A.
