Abstract
The crystal structure and magnetic properties of the pseudobinary system Gd(CoxIr1-x)2 are reported. The compounds crystallise in the C15 Laves phase with a sudden lattice contraction at x=0.4. Magnetic measurements indicate that Co develops a magnetic moment for x>0.4. The onset of this moment is coincident with a sudden contraction of the lattice. Electron spin resonance measurements of g shift and linewidth also show sharp increases at x=0.4. The correlated changes in the various properties are interpreted as due to a movement of the Fermi level as Co is substituted for Ir.Keywords
