Gadolinium is a nearly ideal soft-magnetic material. However, one cannot take advantage of its properties at temperatures higher than the room temperature where Gd loses the ferromagnetic ordering. By using high-purity bulk samples with grains ~200 nm in size, we present proof-of-concept measurements of an increased Curie point (TC) and spontaneous(More)
We report the attainment of the ferromagnetic state in an interstitially modified heavy rare-earth-iron intermetallic compound in an external magnetic field. The starting composition is RE2Fe17, which is the RE-Fe binary richest in iron. We concentrate on the Tm-Fe compound, which is the most sensitive to magnetic field. The maximum possible amount of(More)
Abstract. The antiferromagnetic state, observed in Lu2Fe17 at elevated temperatures, is stabilized in (Lu0.8Ce0.2)2Fe17 over the whole magnetically ordered range below TN = 247 K. The compound exhibits easy-plane magnetic anisotropy and a metamagnetic transition at fields below 1 T. The magnetostriction at the metamagnetic transition was studied by both(More)
Introduction Uranium and cobalt do not form a binary compound with the hexagonal Th2Ni17-type crystal structure but this structure can be stabilized by a small substitution of Co by a third element, e.g. Si or Ge [Berlureau et al., 1993; Chevalier et al., 1996; Shiokawa et al., 1994]. The homogeneity range extends from x = 1.3 to 3 in the U2Co17-xGex system(More)
An experimental study of correlations between the magnetovolume effects and the type of magnetic ordering in the Lu(2)Fe(17)-based intermetallics is shown for the example of variation of the interatomic distances by means of substitution of Ce for Lu, hydrogenation and subsequent high-pressure investigation of both the initial (Lu(0.8)Ce(0.2))(2)Fe(17) and(More)
