Muon-spin-rotation ({mu}{sup +}SR) studies of Bi{sub 2}Sr{sub 3{minus}{ital x}}Y{sub {ital x}}Cu{sub 2}O{sub 8+{ital y}} ({ital x}=0.3, 0.5, 0.6, 0.8, and 1.0) show that the magnetic ordering temperature {ital T}{sub {ital N}} falls rapidly with increasing hole concentration from {ital T}{sub {ital N}}(x=1.0)=210 K to {ital T}{sub {ital N}}(x=0.6)=10 K. In field-cooled high-field measurements Bi{sub 2}Sr{sub 2.7}Y{sub 0.3}Cu{sub 2}BO{sub 8+{ital y}} was found to be superconducting with {ital T}{sub {ital c}}{approx}65 K. The resulting phase diagram reflects a transition from magnetic to superconducting phases with increasing hole concentration similar to that found in studies of YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} and La{sub 2{minus}{ital x}}Sr{sub {ital x}}CuO{sub 4+{ital y}}.
