Abstract

Effects of Zn impurities on the vortex phase diagram of YBa₂ (Cu_1-xZn_x)₃ O_y single crystals with O ≤ × ≤ 0.064 have been investigated in magnetic field up to 18 T. The first-order vortex lattice melting transition and the fielddriven disordering transition are extremely suppressed by small amount of Zn impurities. As for Zn-doped YBCO with x ≥ 0.001, the resistive transition shows a broad temperature dependence due to the second-order vortex glass melting transition, while the field-driven disordering transition survives up to 0.003. These behaviors suggest that disorderes induced by Zn impurities strongly affect the vortex system in comparison with the oxygen deficiency in YBCO.
