Small-angle neutron scattering (SANS) is one of the most important techniques for
microstructure determination, being utilized in a wide range of scientific disciplines, such as …

The study of the manganese oxides, widely known as manganites, that exhibit the “colossal”
magnetoresistance effect is among the main areas of research within the area of strongly …

The fundamental physical properties of doped LaMnO 3, generically termed “manganites,”
and much of the underlying physics, were known more than 40 years ago. This article first …

Condensed matter is one of the most active areas of research in physics. Ev ery year new
materials are discovered with properties that are as challenging as or more than those of the …

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

It is now widely accepted that the magnetic transition in doped manganites that show large
magnetoresistance is a type of percolation effect. This paper demonstrates that the transition …

While basic features of polarons were well recognized a long time ago and have been
described in a number of review papers and textbooks, interest in the role of electron …

The critical properties of perovskite manganite La 0.1 Nd 0.6 Sr 0.3 MnO 3 around the
paramagnetic-ferromagnetic phase transition are investigated through various techniques …

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 …

A nanoscale phase is known to coincide with colossal magnetoresistance (CMR) in
manganites, but its volume fraction is believed to be too small to affect CMR. Here we …
