Abstract Manganese oxides (R, A) MnO 3 (R= La, Y, Bi or rare earth metal, A= non-trivalent
do** element) have been one focus of research for two outstanding properties:(i) …

The question whether La Mn O 3 accepts do** with tetravalent cations such as cerium and
thus allows the preparation of electron-doped mixed-valent lanthanum manganites has …

The current-voltage (IV) characteristics and resistance switching mechanism of Ag∕ La 0.7
Ca 0.3 MnO 3 (LCMO)∕ Pt sandwiched films, which were deposited on Pt∕ Ti∕ SiO 2∕ Si …

A topical and highly promising aspect of the field of spintronics is the physics involved in the
flow of a spin-polarized current through magnetic tunnel structures. This review focuses on …

We report an x-ray absorption spectroscopic (XAS) study on thin films of La 0.7 Ce 0.3 MnO
3. The measurements clearly show that the cerium is in the Ce (IV) valence state, and that …

Epitaxial c-axis oriented Bi Fe O 3 (BFO) thin films were deposited on (001) Nb-doped Sr Ti
O 3 (Nb-STO) substrates by pulsed laser deposition. Introducing Bi vacancies caused the …

Different from the negative colossal magnetoresistance (CMR) of the LaMnO 3 compound
family, a positive CMR has been discovered at low applied magnetic field and high …

We review colossal magnetoresistance in single phase manganites, as related to the field
sensitive spin-charge interactions and phase separation; the rectifying property and …

Nanoconfinement studies in the glass system xNiO-(1-x) SiO 2 having x values as 0.2 and
0.4 were carried out by preparing nanocomposites using mesoporous alumina template …

We show, using superconducting tunneling spectroscopy and tunneling magnetoresistance
measurements, that ferrimagnetic alloys of Co and Gd can exhibit both positive and negative …
