Magnetic properties of the Zr(Cr1-xNix)2 alloys and their hydrides

The magnetic susceptibility has been measured by the Faraday method on the Zr(Cr1-xNix)2 alloys and their hydrides. All the systems investigated were found to exhibit paramagnetism. The Pauli paramagnetism of ZrCr2 is enhanced by substitution of chromium by nickel or by hydrogenation. In the ternary region, besides the Pauli paramagnetism a contribution to the total susceptibility associated either with the presence of a ferromagnetic phase or with a Curie-Weiss type of paramagnetism was observed. The ferromagnetic contribution is attributed to solute nickel atoms in ZrCr2 matrix, while the Curie -Weiss behaviour is associated with the antiferromagnetically coupled magnetic moments in the nickel sublattice. Hydrogen absorption acts in favour of these effects.
