  Abstract The temperature dependence of the electrical resistivity of the REFe 2 compounds (RE = Y, Ce, Gd, Tb, Dy, Ho, Er, Tm, Lu) in the range from 4 K up to 1000 K are presented. The outstanding feature of CeFe 2 is also demonstrated by the temperature dependence of the thermo-power. The analysis of these data reveals that the Fe 3 d moments act as localized moments. This is supported by bandstructure

  Single-crystalline RFe2(110) compounds (R = Y, Sm, Gd, Tb, Dy0.7Tb0.3, py, Fr, and Lu) have been grown by molecular-beam epitaxy. Compared to the bulk compounds, the chin films exhibit modifications of the magnetic anisotropy, related tb the strains induced during deposition. We present here a detailed determination of in-plane and out-of-plane parameters using x-ray and neutron diffraction. RFe2 films and RFe2 /YFe2 bilayers have been deposited on a Nb buffer covered with Fe. Both systems are strained compared to bulk compounds: they are expanded in the plane of epitaxy and compressed along the growth direction. For single RFe2 films, the strains do not depend, on the lattice parameters of the corresponding bulk compounds, i.e., on the large mismatch between the film and the buffer (around 10%). The sign and the values of the strains are explained with a model of differential thermal contraction between the film and the substrate. For RFe2 films involved in RFe2/YFe2 bilayers, the mismatch between RFe2, and the YFe2, layer is smaller and the strains in the RFe2 films do depend on the bulk lattice parameters. Their evolution can be explained with an elastic model. [S0163-1829(99)00107-1].
