We address the problem of the percolative phase separation in polycrystalline samples of Pr
0.5− δ Ca 0. 2+ δ Sr 0.3 MnO 3 for− 0.04<~ δ<~ 0.04 (hole doping n between 0.46 and 0. 5 …

In some hole-doped manganites, the application of various external perturbations can
destabilize Mn 3+/Mn 4+ ordering and favor ferromagnetic interactions, resulting in large …

In this work we present electrical resistivity and magnetization (M) data as a function of
temperature T and magnetic field H of polycrystalline Pr 0.5 Sr 0.5− x Ca x MnO 3 (x= 0.1 …

We study the effect of the introduction of a controlled amount of oxygen vacancies on the
magnetic and transport properties of the phase separated manganite Pr 0.5 Ca 0.2 Sr 0.3 …

The insulator-metal transition in single crystal La 5/8− y Pr y Ca 3/8 MnO 3 with y≈ 0.35 was
studied using synchrotron x-ray diffraction, electric resistivity, magnetic susceptibility, and …

Neutron scattering has been used to investigate the evolution of long-and short-range
charge-ordered (CO), ferromagnetic, and antiferromagnetic (AF) correlations in single …

The phase diagram of Pr 0.65 (Ca y Sr 1− y) 0.35 MnO 3, 0.6<~ y<~ 0. 8, has been
determined by neutron diffraction, magnetization, and electrical conductivity measurements …

Phase separation (PS) in manganites has been suggested to arise as a consequence of
quenched disorder due to the size mismatch of the A-site cations in the perovskite lattice. In …

We report an electron spin resonance (ESR) study of the competing phases at the crossover
from localized to itinerant behaviour on the polycrystalline Pr0. 5 (Ca0. 85Sr0. 15) 0.5 MnO3 …

The nature of phase separation in Pr 0.5 Sr 0.5 MnO 3 has been probed by linear, as well as
nonlinear, magnetic susceptibilities and resistivity measurements across the second order …
