Room temperature ferromagnetism and photoluminescence in Cu doped ZnO nanocrystals
Synthesize of YBa2 Cu3 O7-δ nanoparticles and the coexistence of superconductivity and ferromagnetic phases
analysis the nanoparticles have orthorhombic structure. Room temperature magnetizations measured using a vibrating sample magnetometer (VSM) showed that they have magnetic properties. The development of ferromagnetism is attributed...

Evaluation of electronic and transport properties of a nano-scale device in the presence of electric field
(OSE)
molecule sandwiched between two ferromagnetic electrodes has been carried out. We adopt a modified
Su–Schrieffer–Heeger (SSH) Hamiltonian for describing the isolated Pentathiophene molecule. The
ground state of the molecule...
Co Doped ZnO Nanoparticles: Structural, Morphological, Optical, Magnetic and Antibacterial Studies
Impacts of geology and land use on magnetic susceptibility and selected heavy metals in surface soils of Mashhad plain, northeastern Iran
Magnetic susceptibility is a fast, inexpensive and reliable technique for estimating and monitoring the anthropogenic contamination of soil with heavy metals. However, it is essential to determine the factors affecting ...
Lateral Spin Valve Based on the Two-Dimensional CrN/P/CrN Heterostructure
We propose a spin valve based on a blue-phosphorus monolayer sandwiched between two half-metallic two-dimensional
Cr
N
layers. We use density-functional theory combined with Boltzmann transport theory to investigate ...
Assessment of Nanothermodynamic Properties of Ferromagnetic Nanocluster in Subdivision Potential Approach and Magnetic Field
Using subdivision potential approach and mean-field theory for a ferromagnetic
cluster, we obtained nanothermodynamic properties for a ferromagnetic nanocluster
in the presence and also the absence of the magnetic field...
Removal of Methyl Orange from Aqueous Solutions by Ferromagnetic Fe/Ni Nanoparticles
Herein, the removal of methyl orange (MO), a monoazo dye, from aqueous solutions was investigated using bimetallic ferromagnetic Fe/Ni nanoparticles (NPs) with the average particle size of 12-16 nm. The effect of contact time, pH, temperature...
A comparative study of the magnetoelastic properties of the YFe10V2 and NdFe10V2 compounds,
The magnetoelastic properties of iron-rich REFe10V2 (RE=Nd, Y) compounds were studied via magnetostriction and thermal expansion measurements in the 5–300 K range of temperature in up to 6 T external fields. Results of ...
