Abstract Undoped Sm 0.5 Ca 0.5 MnO 3 and doped Sm 0.5 Ca 0.4 A 0.1 MnO 3 (A= Na and
K) compounds were prepared via the sol–gel chemistry route and the composition was …

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

In this paper, we report an investigation of the ferromagnetic state and the nature of
ferromagnetic transition of nanoparticles of La 0.67 Ca 0.33 MnO 3 using magnetic …

Nanocrystalline Pr 0.65 (Ca 0.7 Sr 0.3) Mn O 3 show large magnetocaloric effect at their

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

The Physics of materials with large magnetoresistance (MR), defined as the percentage
change of electrical resistance with the application of external magnetic field, has been an …

Magnetic and magnetocaloric effects of the polycrystalline La 0.4 Pr 0.3 Ba 0.3 MnO 3
