We report a systematic tracking of consequences of size decrease to nanoscale for charge order (CO) and magnetic properties of electron doped manganite Sm0.35Ca0.65MnO3 by magnetization measurements. The bulk form of this system is charge ordered bel

In this paper we compare the magnetic and electron paramagnetic resonance (EPR) properties of Pr0.5Ca0.5MnO3 (PCMO) and Bi0.5Ca0.5MnO3 (BCMO) charge ordered manganites. PCMO and BCMO samples were prepared by solid state reaction method. A commercial

Ideal two-dimensional (2D) Heisenberg magnets lack long range magnetic order. However, the XY model with spins confined to a plane shows a topological phase transition at a finite temperature corresponding to binding and unbinding of vortices. Experi

Charge ordering is one of the interesting phenomena exhibited by doped rare earth manganites. Along with the application of a high magnetic field and variation of composition and temperature, the intrinsic method of size reduction to nanoscale is a m

We find that the temperature dependence of the Electron Paramagnetic Resonance (EPR) linewidth observed in Bi$_{0.5}$Sr$_{0.5}$Mn$_{0.9}$Cr$_{0.1}$O$_3$ (BSMCO), as well as in certain other 3-dimensional manganites undergoing antiferromagnetic transi

We report on exchange bias effects in 10 nm particles of Pr0.5Ca0.5MnO3 which appear as a result of competing interactions between the ferromagnetic (FM)/anti-ferromagnetic (AFM) phases. The fascinating new observation is the demonstration of the tem

Here we present a comparative study of the temperature dependent magnetic properties of nanosized and bulk samples of Sm 0.08 Ca 0.92 MnO 3 (SCMO) manganite. Nanoparticles of SCMO (mean diameter ∼ 27, 22 and 16 nm) were synthesized by sol-gel techn
