Giant volume magnetostriction in CMR manganites R₁₋xSrxMnO₃ (R = Sm, Nd)
Magnetization, ac initial magnetic susceptibility, resistance, magnetoresistance, thermal expansion and magnetostriction measurements were performed for R₁₋xSrxMnO₃ (R=Sm, x=0.33, 0.40, 0.45; R=Nd, x=0.33, 0.45)compounds. For all compounds in the TC region we have observed a large volume contraction...
