Programming the reaction chemistry for superseding the formation of Sm2O3 in a competitive process of formation and dissolution, the crystal growth patterns are varied and two different nanostructures of Sm2O3 in 2D confinement regime are designed. Among these, the regular and self-assembled square platelets nanostructures exhibit paramagnetic behavior analogous to the bulk Sm2O3. But, the othe...

Hyperfine interactions, magnetic interactions between the spins of electrons and nuclei, in graphene and related carbon nanostructures are studied. By using a combination of accurate first principles calculations on graphene fragments and statistical analysis, I show that both isotropic and dipolar hyperfine interactions in sp2 carbon nanostructures can be accurately described in terms of the l...

In the present study, new multi-components spinel ferrite Zinc doped metallic ferrites are investigated. The synthesized compounds consisting of Zinc copper ferrite nanostructures were developed using the Co-precipitation technique. Powder X-ray diffraction pattern (XRD) confirms the formation of the spinel phase for all the samples. The lattice constant was studied through powder X-ray diffrac...

Microscopy is very important in scientific research, particularly in the development of new materials for several engineering applications including medicine. The recently developed high-Tc superconducting materials and their performance at higher magnetic fields and higher temperatures are crucial important for real applications. The performance properties are mainly controlled by nanostructur...

Tremendous advances in the study of magnetic light-matter interactions have recently been achieved using man-made nanostructures that exhibit and exploit an optical magnetic response. However, naturally occurring emitters can also exhibit magnetic resonances in the form of optical-frequency magnetic-dipole transitions. Here we quantify the magnetic nature of light emission using energy- and mom...

Novel multifunctional magnetic-mesoporous Janus particles with controlled aspect ratio were developed by a simple one-step synthesis approach. Due to their superior magnetic properties and well-defined pore structures, these particles will be important in drug delivery, molecule targeting, cellular imaging, and as building blocks for the assembly of complex nanostructures.

Recent progress in physics on spin dependent transport in magnetic nanostructures is reviewed. Special attention is paid on the spin accumulation and spin current caused by spin injection into non-magnetic metals and semiconductors and superconductors. A variety of phenomena induced in nano-superconductor/ferromagnet devices are proposed, examining the spin-charge separation in superconductors.
