摘要

We report here the electrical resistivity of nanocrystalline perovskite-structured La-Sr manganites as a function of pressures up to 8GPa, at roorn temperature. The nanocrystalline perovskite manganites were prepared by the sol-gel technique and found to have crystallite sizes of 12-18 nm. The pressure dependence of the electrical resistivity shows a first-order phase transition at 0.66(2)GPa and a subtle phase transition between 3.5 and 3.8GPa. The first-order transition at 0.66GPa can be related to the transition front localized-electron to band magnetism.
