OBSERVATION OF MAGNETIC SPIN CORRELATIONS IN THE LUFE10MO2 ALLOY

Results of magnetic, medium-resolution neutron diffraction and small-a ngle neutron scattering (SANS) measurements on a polycrystalline LuFe1 0Mo2 intermetallic alloy show that ferromagnetic (FM) interactions exi st between 5 and 325 K, but finite magnetic spin correlations emerge i n the examined temperature range. It is observed that in zero applied magnetic field there is no well defined critical point T-c indicating a transition from a paramagnetic to a long-range ordered magnetic phas e. A linear variation of magnetization as a function of T-3/2 remarkab ly persists up to a temperature that is a large fraction of the T-c fo r the LuFe12-xMox alloys.
