The copper magnetism of ErBa{sub 2}Cu{sub 3}O{sub 6.2} is examined by transverse-field (TF) and zero-field (ZF) muon-spin relaxation ({mu}SR). These data indicate two magnetic phases with {ital T}{sub {ital N}1}{congruent}330 K and {ital T}{sub {ital N}2}{similar to}65 K. The second phase is signaled by deviation of the ZF-{mu}SR frequencies from a standard magnetization curve and an abrupt change in the TF-{mu}SR relaxation rate. A relaxation feature indicates a muon depolarization mechanism with a {ital T}{sup 3/2} dependence in the low-temperature phase. Observed fields are compared to those calculated for proposed magnetic structures.
