Research

Research of our group is devoted to new magnetic and photonic materials promising in spintronics, magneto-optical and data storage applications, and fundamental studies of spin dynamics in nanoscale and nanostructured magnetic materials. The major research topics include:

Electron magnetic resonance studies of nano-scale systems. Fundamental studies
Earlier, we demonstrated that spin dynamics in magnetic nanoparticles demonstrates special features related to the quantum behavior of the spin cluster. These is the first observation of these quantum features in relatively large objects such as nanoparticles. We continue experiments and theoretical studies to get more information on the spin dynamics of magnetic nanoparticles as a boundary case between purely quantum (reversible) behavior and classical (irreversible) thermodynamics. In particular, the double quantum transitions were studied in random and arranged arrays of magnetic nanoparticles in order to better understand the nature of the effect.

Nuclear magnetic resonance and relaxation in systems with magnetic nanoparticles
Magnetic nanoparticles are promising for many interesting applications in science, technology and biology, including MRI and medical hyperthermia. We conduct experimental studies of nanoparticle-related effects on NMR spectra and spin relazation of the solvent protons. In 2009, effects were studied as functions of particle size and systems viscosity.

Development of magnetic dipole systems for probing optical magnetism
Recent advances in plasmonic-based metamaterials show that magnetic compoent of the optical field can be strongly modified by properties and geometry of metallic nanostructures, leading to such interesting effects as negative magnetic permeability and magnetic resonance in optical range. To probe such effects experimentally, systems containing rare-earth ions having magnetic dipole-related transitions can be used as spectroscopic tools. We develop Eu3+ materials for such probing methods and perform optical studies at nanoscale.

Proton NMR moves on

23 May 2007A new study on the proton nuclear magnetic resonance (NMR) spectra of a novel class of magnetorheological nanofluids could help scientists distinguish between healthy and damaged tissues in the human body. Natalia Noginova of Norfolk State University in the US and colleagues have found that suspensions of γ-iron oxide nanoparticles affect spin relaxation in liquids surrounding the nanoparticles. The effects are different from those in solids and vary for different liquids.
