Inelastic light scattering is an intensively used tool in the study of electronic properties of
solids. Triggered by the discovery of high-temperature superconductivity in the cuprates and …

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

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 …

We present a rationalization of the Raman spectra of orthorhombic and rhombohedral,
stoichiometric and doped, manganese perovskites. In particular, we study R MnO 3 (R= La …

The perovskite‐like manganites R1− xAxMnO3, where R is a trivalent rare earth or Y and A
is a divalent alkaline earth element, are characterized by a strong interplay of magnetism …

LaMeO3 (Me: Mn, Fe and Co) perovskites, obtained by polymerizable complex method at
900° C for 6 h with grain size of∼ 80 nm, were examined by X-ray diffraction (XRD) …

The mixed-valence perovskitelike manganites are characterized by the unique interrelation
of Jahn-Teller distortions, electric and magnetic properties. The Jahn-Teller distortion follows …

We have studied the behavior of the Raman phonons of a stoichiometric LaMnO 3 single
crystal as a function of temperature in the range between 77 K and 900 K. We focus on the …

Abstract Rare-earth (Re) manganites (with alkaline-earth (Ak) ions partially substituting
them), ie Re 1− x Ak x MnO 3, have been intensively explored for the last decade or more …

We report results of a high-pressure investigation by Raman spectroscopy of a classic
relaxor ferroelectric (relaxor) PbMg 1/3 Nb 2/3 O 3 (PMN), which is considered to be a model …
