The new rare-earth nickel polyborides R 2 NiB 10 ( R =Y, Ce–Nd, Sm, Gd–Ho) were prepared by reacting cold-pressed pellets of the elemental components in an arc-melting furnace, followed by annealing in evacuated silica tubes. They crystallize wit

The magnetic properties of the ten title compounds were investigated with a SQUID magnetometer in the temperature range of 2–400 K with magnetic flux densities up to 5.5 T. The magnetic susceptibilities of the two lanthanum compounds indicate that
