The spin reorientation in ErCo10-xFexMo2 (x = 0, 1, 2, 3 and 4) compounds has been studied by
measurements of the temperature dependence of the magnetization. The spin reorientation in this system is
due to the competing anisotropies of the erbium and the transition-metal sublattice. A decrease of the
transition-metal sublattice anisotropy is believed to be the reason of the observed increase of the spinreorientation
temperature with increasing Fe content. ?? 2002 Elsevier Science B.V. All rights reserved.
