摘要：

Tm2Cu2In belonging to the family of R2T2X intermetallics is a ferromagnet with glassy features. This work de-scribes results of high-pressure studies of its magnetic behavior. While TC exhibits only a weak and non -monotonous response to hydrostatic pressure, the pressure impact on frequency dependence of AC susceptibil-ity can be interpreted as due to gradual increase of relaxation time and decrease of the activation energy barrier. Since the magnetic behavior is strongly related to the details of crystal structure, the temperature and pressure effects on the lattice are presented, as well. First principles calculations based on the density functional theory provide a background information.
