Anisotropy of magnetoelastic phenomena in Lu2Fel7 intermetallics

The anisotropy of magnetoelastic phenomena that accompanies changes of magnetic structures in the Lu2Fe17 intermetallics was studied under pressure. A huge anisotropy in compression (d In c/dp ~ 2d/n a/dp) and thermal expansion (d lnc/dT=-5d In a/dT) of the Lu7Fe17 crystal lattice has been observed...

Description
Summary:The anisotropy of magnetoelastic phenomena that accompanies changes of magnetic structures in the Lu2Fe17 intermetallics was studied under pressure. A huge anisotropy in compression (d In c/dp ~ 2d/n a/dp) and thermal expansion (d lnc/dT=-5d In a/dT) of the Lu7Fe17 crystal lattice has been observed under hydrostatic pressure, using micro-strain gauges fixed on the single crystal along principal axes. The dominant role of the lattice c-parameter in the pressure effects is discussed.
