文摘

La0.7Ca0.2Sr0.1MnO3 was elaborated by solid-state reaction (S1) and sol-gel route (S2). Critical exponents for S1 are close to the tricritical mean field model. Critical exponents for S2 are close to the mean field model. The critical behavior of our sample depend havely on the synthesis technique.
