Antiferromagnetic-insulating (AF-I) and ferromagnetic-metallic (FM-M) phases coexist in various half-doped manganites over a range of temperature and magnetic field, and this is often believed to be an essential ingredient of their colossal magnetoresistance. We present magnetization and resistivity measurements on Pr0.5Ca0.5Mn0.975Al0.025O3 and Pr0.5Sr0.5MnO3 showing that the fraction of the two coexisting phases at low temperature in any specified measuring field, H, can be continuously… 
Enhancement of equilibrium fraction in La0.5Ca0.5MnO3 by recrystallization
The nature of the coexisting ferromagnetic–metallic (FMM) and antiferromagnetic–insulating (AFI) phases in a La0.5Ca0.5MnO3 sample is explored through magnetization and resistivity studies. Like many
Tunable two-phase coexistence in half-doped manganites
We discuss our very interesting experimental observation that the low-temperature two-phase coexistence in half-doped manganites is multi-valued (at any field) in that we can tune the coexisting
Devitrification of a glass-like arrested ferromagnetic phase in La0.5Ca0.5MnO3
Magnetization measurements in La0.5Ca0.5MnO3 manganite show that the high-temperature long-range ferromagnetic-metallic phase transforms to antiferromagnetic-insulating phase, although a fraction of
Field dependence of temperature induced irreversible transformations of magnetic phases in Pr0.5Ca0.5Mn0.975Al0.025O3 crystalline oxide
Glass-like arrest has recently been reported in various magnetic materials. As in structural glasses, the kinetics of a first order transformation is arrested while retaining the higher entropy phase
Low temperature studies of Bi doped Pr0.6Sr0.4MnO3 manganites: magnetization and magneto-transport
Low temperature magnetization and resistivity measurements of bismuth (Bi) doped Pr0.6−xBixSr0.4MnO3 (x = 0.2, 0.23 and 0.25) manganites synthesized by solid state reaction method are reported here.
Neutron diffraction evidence for kinetic arrest of first order magneto-structural phase transitions in some functional magnetic materials
The cooling and heating under unequal fields protocol has been used to establish phase coexistence of metastable and equilibrium states, and also to demonstrate the devitrification of the arrested metastable states in the neutron diffraction patterns.
Tuning the phase transition dynamics by variation of cooling field and metastable phase fraction in Al doped Pr0.5Ca0.5MnO3
It is rather significant that in spite of the metastable phase fraction calculated from resistivity being somewhat off that of magnetization, their cooling field dependence exhibits a striking similarity, which indicates that the dynamics in arrested and unarrested regimes are so different that it comes out vividly provided that the measurements are performed around the percolation threshold.


Relating supercooling and glass-like arrest of kinetics for phase separated systems: Doped CeFe 2 and (La,Pr,Ca)MnO 3
Coexisting ferromagnetic and antiferromagnetic phases over a range of temperature as well as magnetic field have been reported in many materials of current interest, showing disorder-broadened
Charge-ordered ferromagnetic phase in La0.5Ca0.5MnO3
Mixed-valent manganites are noted for their unusual magnetic, electronic and structural phase transitions. For example, the La1-xCaxMnO3 phase diagram shows that below transition temperatures in the
Strain-induced metal–insulator phase coexistence in perovskite manganites
It is shown that the texturing can be due to the intrinsic complexity of a system with strong coupling between the electronic and elastic degrees of freedom, which leads to local energetically favourable configurations and provides a natural mechanism for the self-organized inhomogeneities over both nanometre and micrometre scales.
Magnetic imaging of a supercooling glass transition in a weakly disordered ferromagnet
The results show that the observed static magnetic configuration seen below the glass-transition temperature arises from the cooperative freezing of the first-order antiferromagnetic (charge ordered) to ferromagnetic transition, and suggest that accommodation strain is important in the kinetics of the phase transition.
Electronically soft phases in manganites
This work argues that magnetic and charge modulation coexist in new thermodynamic phases, and argues for a fundamental reinterpretation of the nature of charge modulation in these materials, from a localized to a more extended ‘charge-density wave’ picture.

Imaging the vortex-lattice melting process in the presence of disorder
A differential magneto-optical technique is used to obtain direct experimental visualization of the melting process in a disordered superconductor, revealing complex behaviour in nucleation, pattern formation, and solid–liquid interface coarsening and pinning.
Ultrasharp magnetization steps in perovskite manganites.
Detailed study of steplike metamagnetic transitions in polycrystalline Pr0.95Co0.05O3.5Ca0.5Mn0.75O3, showing that the steps are an intrinsic property, qualitatively different from either previously observed higher temperature metam Magnetic transitions in the manganites or metam electromagnetic transitions observed in other materials.
