Abstract:
The results of the investigation of temperature dependences of longitudinal and torsional sound wave velocities and the internal friction of FeGe2 tetragonal single crystal along [100], [110] and [001] crystallographic axes have been presented. At temperatures of magnetic phase transitions of T1≈ 263 K and T2≈ 289 K an abrupt decrease of sound velocities is observed. The profound anisotropy of the internal friction is detected in the region of the existence of incommensurate magnetic structure (T1⩽T⩽T2).
This work was performed in the framework of state task of the Ministry of Education and Science of the Russian Federation (theme “Spin” no. AAAA-A18-118020290104-2.
