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

For disordered Heisenberg systems with small single ion anisotropy (D), two spin-glass (SG)
transitions below the long-range ordered (LRO) phase transition temperature (T c) have …

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

La 0.8 Ca 0.2 MnO 3 particles with the sizes from 17 to 43 nm have been prepared using the
sol-gel method and the magnetic properties are systematically studied. The existence of the …

Recent studies on nanosized near half-doped manganites reported that the charge-ordered
antiferromagnetic states present in their bulk counterparts are strongly suppressed and that …

We report detailed dc magnetization and linear and nonlinear ac susceptibility
measurements on the hole doped disordered cobaltite La 0.5 Ba 0.5 CoO 3. Our results …

The bulk and nanocrystalline samples of half doped, rare earth, perovskite manganites, Ln0.
5Ca0. 5MnO3 (Ln= La, Nd, Pr) were investigated by X-ray diffraction and magnetic …

Abstract In this study, La 0.625 Ca 0.315 Sr 0.06 MnO 3 (LCSMO) nanoparticles were
prepared by facile sol-gel method at low crystallization temperatures. Various test methods …

Here, we report both ac and dc magnetization, thermodynamic, and electric properties of
hexagonal Ba 3 NiIr 2 O 9. Ni 2+(spin 1) forms a layered triangular lattice and interacts …

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 …
