Abstract
We present inelastic neutron scattering measurements and ¯rst principles calculations examining
the intermetallic marcasite CrSb2. The observed spin wave dispersion implies that the magnetic
interactions are strongly one-dimensional with antiferromagnetic chains parallel to the crystalline
c-axis. Such low-dimensional excitations are unexpected in a semiconducting intermetallic system.
Moreover this material may be further interesting in that the magnetic anisotropy may enhance
thermoelectric properties along particular crystallographic directions.
