Novel methods for ultrasound excitation in magnetic materials is used. Transverse, longitudinal, Lamb waves velocities are measured with high accuracy from resonance frequencies. Sample shape is a thin disk.

Elastic constants of semimagnetic semiconductors A_1-xB_xMnO₃ (A is rare earth, B - 2⁺ metal) were investigated as a function of content x, temperature and magnetic field.

Magnetic properties of intermetallics (Kondo-magnets, heavy fermions systems etc.) are investigated.

We are focused on the interplay of magnetic, electronic and crystalline systems of rare-earth metals with long-periodic magnetic structures (helical, sine etc.).
