Perovskite manganites exhibit a broad range of structural, electronic, and magnetic
properties, which are widely investigated since the discovery of the colossal …

In this paper we report the structural and property (magnetic and electrical transport)
measurements of nanocrystals of half-doped La 0.5 Ca 0.5 MnO 3 (LCMO) synthesized by …

This chapter attempts to systematically outline some fundamentals and key experimental
results concerning magnetic properties of perovskite manganites, focusing on (i) …

Most previous investigations have shown that the surface of a ferromagnetic material may
have antiferromagnetic tendencies. However, experimentally, the opposite effect has been …

Recent experiments showed that the robust charge ordering in manganites can be
weakened by reducing the grain size down to nanoscale. Weak ferromagnetism was …

We report the significantly improved magnetocaloric properties of sol–gel prepared
nanocrystalline samples of LaMnO3 with average particle size∼ 200nm and∼ 40nm in …

Nanocrystalline Pr 0.65 (Ca 0.7 Sr 0.3) Mn O 3 show large magnetocaloric effect at their
charge order transition temperature (T CO) as well as at the temperature at which the …

The magnetic properties and the effects of interparticle interaction on them have been
studied in nanoparticles of half-doped Pr 0.5 Sr 0.5 MnO 3. Three samples consisting of …

La 0.4 Ca 0.6 Mn O 3 nanoparticles of grain size as small as∼ 20 nm are prepared and their
magnetic behaviors are investigated in order to understand the size effect of the charge …

Abstract Pr 0.65 Ca 0.25 Cd 0.1 MnO 3 ceramic was elaborated using the conventional solid-
state reaction technique. The polycrystalline sample was subjected to investigate by ac …
