Disorder of anisotropy is introduced into spin 1/2 quantum XXZ chains. This model, which is refered as the spin 1/2 + Jz chain, is studied by the quantum Monte Carlo method. It displays the critical phenomena of the x-y phase, though the critical exponents ),, r/ and v must be corrected. However, th
