Abstract

Abstract Magnetic measurements were made on the compounds EuGe, DyGe and TmGe. The first two compounds order antiferromagnetically at 20 K and 37 K respectively. For TmGe antiferromagnetic ordering is observed below 4.2 K. The magnetic structure of orthorhombic DyGe was investigated by neutron diffraction and shown to be antiferromagnetic with propagation vector k = [00 1 2 ]. The magnetic properties of all RGe compounds (R ≡ rare earth metal) are reviewed. It is shown that the magnetic coupling constant changes from positive to negative as the RGe series is passed through.
