N2 - We report on neutron diffraction, specific heat and μSR studies of the edge-sharing spin-chain compound Ca2+xY2-xCu 5O10. At small and intermediate hole doping (x<1) the ordered Cu moment decreases rapidly. Above x = 1 the long-range magnetic order disappears. The magnetic system develops into a state, where a spin-chain regime and static magnetic configurations formed by the residual spins coexist. Near x = 2 the static configurations are washed out. Only a spin-chain component is observed in the heavily doped sample in which long-range order recovers.
