High-field magnetoconductance in La-Sr manganites of FM and AFM ground states

Popis výsledku v původním jazyce

Large-grain La1–xSrxMnO3 ceramic samples of compositions x=0.45 and 0.55, representing the ferromagnetic (FM) and A-type antiferromagnetic (AFM) ground states, were produced via classical sintering at 1500 °C of cold-pressed sol-gel prepared single-phase nanoparticles. Using the same precursors, nanogranular forms of both manganite ceramics were prepared by fast spark plasma sintering at low temperature of 900 °C, which limits the growth of crystal grains. The magnetotransport of both the bulk and nanogranular forms was investigated in a broad range of magnetic fields up to 130 kOe and analyzed on the basis of detailed magnetic measurements. For interpretation of observed behaviors, the theory of grain-boundary tunneling is revisited.
