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.
