Scope of Activities

Scientific activity is focused on the advanced multifunctional materials including soft magnetic materials, magnetic composites, magnetic nanopowders and ferroelectric materials. In the group of magnetic materials iron based amorphous and nanocrystalline alloys are extensively explored. Special attention is paid to the so called enhancement of soft magnetic properties effect, structural relaxation and nanocrystallization. The aim is to find correlations between material microstructure (e.g. the relaxed amorphous phase) and physical properties (permeability, magnetic loss, magnetostriction, magneto-impedance effect, resistivity etc.). In the group of powder materials we produce ferrite nanopowders of spinel structure and for such powders superparamagnetism and/or super spin glass like effects are extensively examined. Moreover, the powder is also used as a component of magnetic composite materials for which the usage parameters are determined.

In the field of coating materials we concentrate on mechanical properties i.e. on determination of the so-called apparent Young modulus (coating – substrate) and the adhesion coefficient via measuring and analyzing the flexural vibrations of a rectangular sample.

In the group of ferroelectric multifunctional materials linear and nonlinear dielectric response of materials with various types of electric ordering is investigated. This includes systems such as ferroelectrics, dipolar glasses and relaxor ferroelectrics. Our equipment enables investigations of dynamics of elementary polarization processes in dielectric materials with potential applications in electronics as well as an experimental verification of available theoretical models.
