FUNCTIONAL MATERIALS GROUP
The group studies smart materials with functional properties: magnetic shape memory, shape memory, magnetoelastic, giant magnetostriction, unusual thermal expansion. The main scientific interest is fundamental study of the magnetic shape memory and its thermal-
Main scientific results in the field of Magnetic Shape Memory:
Giant MSME of 5% due to rotation of the magnetic field is obtained under low magnetic field value (H=0,25-
Reversible strain up to 3% was obtained in the magnetic field and compressive stress applied together in the orthogonal directions at room temperature, which is a real model for actuating element (2000).
New physical phenomenon-
Temperature stability of martensite and magnetic-
Crystalline structure of martensite in the alloy showing giant MFIS of 5% was clarified with X-
