Superconducting magnetoresistance in ferromagnet/superconductor/ferromagnet trilayers [PDF]

Scientific Reports, 2015
Abstract Magnetoresistance is a multifaceted effect reflecting the diverse transport mechanisms exhibited by different kinds of plain materials and hybrid nanostructures; among other, giant, colossal and extraordinary magnetoresistance versions exist, with the notation indicative of the intensity. Here we report on the superconducting

Interplay between carrier and cationic defect concentration in ferromagnetism of anatase Ti1-xTaxO2 thin films

AIP Advances, 2012
Thin films of Ta incorporated TiO2 grown by pulsed laser deposition under specific growth conditions show room temperature ferromagnetism. Ta introduces carriers and concomitantly cationic defects, the combination of which leads to ferromagnetism.

Sm-Eu Co-Doped BiFeO3 Nanoparticles With Superabsorption and Electrochemical Oxygen Evolution Reaction

Frontiers in Physics, 2022
Bi0.95Sm0.05Fe1−xEuxO3 (x = 0, 0.05, 0.10, 0.15) nanoparticles were prepared via a two-solvent sol–gel method. The X-ray diffraction (XRD) and Raman results suggested that the main phase of the samples gradually evolved from perovskite phase R3c to ...

Manipulation of the Ferromagnetism in LaCoO3 Thin Films Through Cation‐Stoichiometric Engineering

Advanced Electronic Materials, 2023
Spin‐state transitions are an important research topic in complex oxides with the diverse magnetic states involved. In particular, the low‐spin to high‐spin transition in LaCoO3 thin films has drawn a wide range of attention due to the emergent ...

Gate-induced band ferromagnetism in an organic polymer

, 2001
We propose that a chain of five-membered rings (polyaminotriazole) should be ferromagnetic with an appropriate doping that is envisaged to be feasible with an FET structure.

Ferromagnetism in Defected TMD (MoX₂, X = S, Se) Monolayer and Its Sustainability under O₂, O₃, and H₂O Gas Exposure: DFT Study

Nanomaterials, 2023
Spin-polarized density-functional theory (DFT) has been employed to study the effects of atmospheric gases on the electronic and magnetic properties of a defective transition-metal dichalcogenide (TMD) monolayer, MoX2 with X = S or Se. This study focuses

Enhancement of ferromagnetism by p-wave Cooper pairing in superconducting ferromagnets

, 2009
In superconducting ferromagnets for which the Curie temperature $T_{m}$ exceeds the superconducting transition temperature $T_{c}$, it was suggested that ferromagnetic spin fluctuations could lead to superconductivity with p-wave spin triplet Cooper ...

Enhanced Ferromagnetic Stability in Cu Doped Passivated GaN Nanowires

, 2008
Density functional calculations are performed to investigate the room temperature ferromagnetism in GaN:Cu nanowires (NWs). Our results indicate that two Cu dopants are most stable when they are near each other.
