Abstrakt: Abstract: Transverse field studies (0.3 T) in HoBa2Cu3O7, DyBa2Cu3O7 and ErBa2Cu3O7 (x=6.40. 6.45, 6.53, 7) were undertaken with the aim of detecting a possible 4f-moment inducedμ + Knight shift which could elucidate the nature of the magnetic coupling among the 4f-moments and a possible interference with superconductivity. AboveT c no shift could be detected in any of the systems except in HoBa2Cu3O7 where a split signal appears involving a positive and a negative shift. Unexpected shifts may be present belowT c .
