EXPERIENCE

General: Development of the magnetic caridiograph, based on SQUID-magentometer, ion and electron pulsed source for irradiation of materials. 7 years experience as a scientific secretary of the large scale international intergovermental user facility - Frank Laboratory for Neutron Physics. Responsibility for planning, reporting, international collaboration, organizing of meeting, workshops, scheduling of experimental facility, cooperation with scientific and industrial partners, representing of the facility at the different international conferences, public relations. Participating and coordination of some international scientific projects in the frame of BMBF, DFG, Helmholtz-RFBR, INTAS etc.

Instrumentation: Many years experience using different spectroscopical methods for study of physical properties of materials, such as complex transition metals oxides, multiferroic, cerium and uranium ternary compounds, high-Tc superconductors at extreme external conditions: low and very low temperature, high magnetic field, high pressure. Experiments on modern synchrotron radiation sources such as ESRF (EXAFS, XMCD, inelastic X-ray scattering, diffraction), DESY/Doris (EXAFS, diffraction), PSI/SLS (diffraction), HZB/BESSY (EXAFS), KIT/ANKA (diffraction) have been performed during last years.

SINQ source in PSI: Several years work as instrument scientist at the high intensity powder neutron diffractometer DMC dedicated to magnetic scattering experiments. Responsibility for the users service, instrument development and own scientific program.

BER-2 reactor in HMI: Several years work as instrument scientist at the single crystal neutron diffractometer E4  and than at the three-axis spectrometer with polarization analysis E1. Responsibility for the users service, instrument upgrade and development and own scientific program.

IBR-2 reactor in JINR: Co-responsible for the  High Resolution Neutron Fourier diffractometer HRFD. Responsibility for the users service, instrument development and own scientific program.

KIT: Responsible for assembling, construction and adjustment of the new high resolution time-of-flight neutron diffractometer EPSILON (BMBF project), developing and implementation a scientific program focusing on study of the magnetic and structural properties of novell materials by neutron (Epsilon) and synchrotron radiation techniques (ANKA-KIT, ESRF, BESSY).

Other facilities: Experiments at the neutron spectormeters in LLB (Saclay)

Scientific activity:

-         magnetism in strong correlated electron systems with perovskite-type structure

-         nature of the magetic phase transitions in uranium ternanry compounds

-         structural effects induced in materials, irradiated by pulsed electron beam

-         precise structure studies of high-Tc superconductors

Other activity:

Lecturer at the several schools for young scientists and specialists in HZB-Berlin and JINR-Dubna, scientific secretary and chairman of some international conferencies in the fields of using neutrons and synchrotron radiation in condenced matter physics Lectures for students and PhD students in Karlsruhe Institute of Technology and Immanuil Kant Baltic University.

-         nature of the magetic phase transitions in uranium ternanry compounds

We studied intermetallic ternanry compound UT2X2-type (T = 3d, 4d, 5d transition metal, in our studies – Pd, Fe, Ru, Ni, Cu, X = Ge, Si) with neutron scattering and µSR. We refine temperature dependence of magnetic phase transitions in U(Pd1-xFex)2Ge2 and showed that magnetic properties could not be explained in terms of the “f-d hybridization model” by modification of hybridization matrix element, but could be explained by RKKY-type indirect exchange interaction.
