Abstract

The effect of preparation pressure on the structural, magnetic and electronic properties is investigated for nanostructured bulk samples of La_2/3Sr_1/3MnO₃. The results show that the grain size decreases and magnetoresistance varies with preparation pressure growth. Low-field magnetoresistance weakens in the whole experimental temperature range when preparation pressure increases, which can mainly attribute to strong-link grain boundaries of samples under high preparation pressure. And high-field magnetoresistance gradually becomes stronger at T<200 K, however becomes weaker at T>200 K with the increase of preparation pressure, which can mainly due to the change of grain size caused by preparation pressure.
