Abstract

We have studied the spin-glass behavior of nonsuperconducting La_2\ensuremath-xSr_xCu_0.95Zn_0.05O₄ (x=0.10--0.22). As in the superconducting analogs of these samples the spin-glass transition temperature T_g decreases with increasing x and vanishes at x=0.19. A local enhancement in T_g at x=0.12 is also observed and attributed to stripe ordering. The disappearance of T_g for x>~0.19 is discussed in terms of a quantum phase transition.
