Nickel oxide (NiO) nanoparticles of nominal size range 16nm and 25nm were obtained by
controlling the calcination temperature. These particles were prepared by the precipitation …

We study gravitational lensing in the vicinity of a slowly rotating massive object surrounded
by a plasma. We have studied two effects:(i) the influence of the frame dragging on the …

We report the magnetic and microstructural properties of antiferromagnetic MnO
nanoparticles with shells of ferrimagnetic Mn 3 O 4, which is opposite the usual arrangement …

The magnetic properties of bimagnetic core/shell nanoparticles consisting of an
antiferromagnetic MnO core and a ferrimagnetic passivation shell have been investigated. It …

Contrast agents (CAs) play a critical role in high-resolution magnetic resonance imaging
(MRI) applications to enhance the low intrinsic sensitivity of MRI. Manganese oxide …

We herein report a comprehensive investigation on the magnetic, structural, and electric
properties of CoO nanoparticles with different sizes by local inspection through hyperfine …

Copper oxide (CuO) nanoparticles with an average size of 25 nm were prepared by a sol–
gel method. A detailed study was made of the magnetization of CuO nanoparticles using a …

The local defect structure of NiO nanoparticles was determined by extended x-ray
absorption fine structure method. By using the bulk and surface sensitive characterization …

We synthesized manganese oxide (MnO and Mn3O4) nanocrystals with various sizes and
shapes by the thermal reaction of a MnII–oleate complex through a “heat‐up process”. When …

Based on the Heisenberg model taking into account single-ion anisotropy and using a
Green's function technique we have studied the influence of size and anisotropy effects on …
