Plasmonic systems: plasmon drag effect

Coupling of photonic, plasmonic and electrical effects have been studied in plasmonic systems. Strong enhancement of photoinduced electric currents was observed in nanostructured systems. We found that the effect is related to plasmon excitation and propagation. An inverse effect – galvanic modulation of plasmons - has been demonstrated as well. These findings can have a great impact as they provide possibility for direct incorporation of plasmonic elements into electronic circuits.

Development of spectroscopic tools for metamaterials studies

Rare earth ions, such Eu3+, having both electric and magnetic dipole-related transitions can provide unique opportunity to probe and map distributions of optical magnetic and electric fields in plasmonic systems. The effects of local optical environment on spontaneous emission spectra, kinetics and radiation patterns of Eu3+ was studied in the conditions of plasmon resonances. We showed that effects are different for electric and magnetic dipoles, and developed the setup for spectroscopic mapping of metamaterials. Current studies involve mapping of systems with optical magnetism and NSOM spectroscopic studies.

Electron magnetic resonance studies of nanoscale systems: Fundamental studies

Earlier, we demonstrated that electron magnetic resonance in magnetic nanoparticles demonstrates features related to the quantum behavior of a giant spin cluster, including multiple quantum transitions. Changes in the shape of the main resonance and magnitude of quantum features were studied as the function of the particle size and temperature. 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.

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. Our experimental studies of nanoparticle-related effects observed in NMR spectra and spin relaxation demonstrate very high sensitivity of spin relaxation times, T1, to the molecular motion. The magnitude of the effects depends on the particle size. Ultra-fine iron oxide particles are found to be most promising for biomedical imaging based on T1 based contrast.

Magentic nanocomposite for tunable metamaterials

We explore a possibility to create tunable metamaterials for microwave applications, such as suspensions of magnetic nanoparticles in polymer composites. In dense systems with 5 nm and 10 nm iron oxide particles, we successfully demonstrated tuning of magnetic permeability in a broad range from negative to positive values with external magnetic field. Current research includes multilayered systems with high magnetic susceptibility materials.
