Abstract :
The Zr3(Rh(1-y)Pdy)4 system in the Pu3Pd4 structure, reported on previously, is further investigated here. It exhibits an incommensurate density wave for 0.04 ⩽y⩽ 0.06, accompanied by strongly varying paramagnetism. It displays weak ferromagnetism at one composition and weak superconductivity at an other. Changes in cooperative behavior with such small changes in composition are unique for a metallic system. The present results indicate that there is a charge density wave of constant wave vector direction and varying lattice displacements in this composition range, with microcracks developing for y=0.04
