HomeScientific research ...
My research activity is now focused on magnetism of solids and phase transitions in solids.
My scientific skills and expirience cover material charactrization, magnetic materials and magnetism, superconductivity,
spintronics, phase transitions, high temperature superconductivity, magneto-resistance, electron spin resonance,
magnetometry, anisotropy, lattice dynamics, seebeck coefficient, single crystal growth.
I am an author of over 90 publications. Below you can find some of my recent publications.
