Low temperature magnetic order of the new ternary rare earth compounds (RRuB4) with the YCrB4-type structure

[[abstract]]Low temperature magnetic susceptibility and electrical resistivity measurements have been carried out for the ternary rare earth ruthenium borides RRuB4 (R≡Gd, Tb, Dy, Ho, Er, Tm, Lu and Y) with the orthorhombic YCrB4-type structure. Ferromagnetic order was observed for all magnetic compounds except R≡Tm, where no transition was observed above 2 K. For the nonmagnetic compound YRuB4 the superconducting transition at 1.4 K was confirmed with onset at 1.36 K in the present study[[fileno]]2010102010131[[department]]物理
