Magnetic cooling technology based on the magnetocaloric effect is a prominent research
topic due to its great potential helps to solve the increasing energy need and environmental …

In this work, we review three models of magnetic ordering in typical magnetic materials that
have been proposed based on atomic physics. The first model we discuss is the O 2p …

In this paper, we investigated the primary reduction and oxygen replenishing processes over
Mn substitutionally doped CeO2 (111) surfaces by density functional theory with the on-site …

Oxygen vacancy in different oxide systems shows up as a crucial parameter in modulation of
the emerging application-oriented functionalities. A systematic exploration on the relation …

A model with two channels of electrical transport (TCET) for perovskite manganites is
proposed, and it is described by an equivalent device with two current-carrier channels. In …

X-ray photoelectron spectra of the O 1s electrons of MnFe 2 O 4, ZnFe 2 O 4, ZnO, and CaO
were used to estimate the average valence, V alO, of the oxygen anions in these samples …

The valence band structures of Al–N-codoped [ZnO:(Al, N)] and N-doped (ZnO: N) ZnO films
were studied by normal and soft x-ray photoelectron spectroscopy. The valence-band …

The dependence of the magnetic moment of the perovskite manganites La 1− x Sr x MnO 3
on the Sr doping level, x, is fitted using an oxygen 2p itinerant electron model for magnetic …

In the present investigation, we present the comparison of the structural, magnetic,
magnetocaloric and magnetoresistance behavior of solid state and sol–gel derived La0 …

We present a comprehensive experimental study on the magnetic and magnetocaloric
properties of a charge-ordered single-crystalline Sm 0.5 Ca 0.25 Sr 0.25 MnO 3 compound …
