The perovskite manganites with generic formula RE 1− x AE x MnO 3 (RE= rare earth, AE=
Ca, Sr, Ba and Pb) have drawn considerable attention, especially following the discovery of …

The evolution of the Griffiths phase (GP) with a ferromagnetic metal (FMM) cluster above the
Curie temperature (TC) and its effect on the magnetic properties, electrical transport …

Magnetic oxides show a variety of extrinsic magnetotransport phenomena: grain-boundary,
tunnelling and domain-wall magnetoresistance. In view of these phenomena the role of …

Several classes of materials are currently under investigation as potential high-spin-
polarization materials. Unfortunately, the proposed half-metallic materials, including the …

Ferromagnetic (FM) manganites, a group of likely half-metallic oxides, are of special interest
not only because they are a testing ground for the classical double-exchange interaction …

Based on the analysis of crystal structure, Mn 3+/Mn 4+ pairs, distortion of MnO 6
octahedron, and electrical transport properties of La 1-x Ca x MnO 3 and La 1-x Sr x MnO 3 …

Phonons in nearly optimally doped HgBa 2 CuO 4+ δ were studied by inelastic x-ray
scattering. The dispersion of the low-energy modes is well described by a shell model, while …

For the perovskite manganite La 1-x Ca x MnO 3, achieving high temperature coefficient of
resistance (TCR) and magnetoresistance (MR) is the key to realize its potential applications …

Neutron scattering measurements on a bilayer manganite near optimal doping show that the
short-range polaron correlations are completely dynamic at high T, but then freeze upon …

Neutron elastic, inelastic, and high-energy x-ray scattering techniques are used to explore
the nature of the polaron order and dynamics in the colossal magnetoresistive (CMR) …
