摘要：

We study the Neel temperature of quasi-one-dimensional S=1/2 antiferromagnets containing nonmagnetic impurities. We first consider the temperature dependence of the staggered susceptibility of finite chains with open boundary conditions, which shows an interesting difference for even and odd length chains. We then use a mean field theory treatment to incorporate the three-dimensional interchain couplings. The resulting Neel temperature shows a pronounced drop as a function of doping by up to a factor of 5.
