[HTML][HTML] Emergence of ferromagnetism and metallicity in Pr0. 5Sr0. 5MnO3 nanoparticles
In this paper, we have studied low-temperature magnetic properties and transport dynamics
of half-doped Pr 0.5 Sr 0.5 MnO 3 (PSMO) nano-manganite. Nanoparticles with different
average grain sizes are synthesized using chemical pyrophoric reaction route and exhibit
same crystal structure. It is reported that particle size reduction in half-doped PSMO
manganite interestingly leads to ferromagnetic (FM) metallic behavior which is accompanied
by coupled positive magnetoresistance (PMR)(up to 9%) at fields (H≤ 1kOe at 50K) and …
