Single-crystal growth and dependences on the hole concentration and magnetic field of the magnetic ground state in the edge-sharing CuO${}_2$ chain system Ca${}_{2+x}$Y${}_{2-x}$Cu${}_5$O${}_{10}$

We have succeeded in growing large-size single-crystals of Ca${}_{2+x}$Y${}_{2-x}$Cu${}_5$O${}_{10}$ with $0\le x\le 1.67$ and measured the magnetic susceptibility, specific heat and mag…
