The spin rotation which takes place in the ternary cubic Laves phase compound Ho0.6Tb0.4Fe2 was studied by means of neutron diffraction and Mössbauer-effect spectroscopy. The neutron diffraction measurements were carried out on an aligned powder sample as a function of temperature (4.2-300 K) and external magnetic field (0-8 kOe). Mössbauer spectra of 57Fe were obtained over a 77-200-K temperature range. The spin rotation in Ho0.6Tb0.4Fe2 is found to take place over the temperature interval 90-140 K. The experimental results enable the determination of the direction of the ferrimagnetic axis as a function of temperature within the spin-rotation interval.
