Peculiarities of the volume magnetostriction in La₁₋xSrxMnO₃ in the Curie point region

Peculiarities of the volume magnetostriction in La₁₋xSrxMnO₃ in the Curie point region

The parallel λ∥ and perpendicular λ⊥ magnetostriction (with respect to the applied magnetic field) and the thermal expansion Δl/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 magnetost...
