摘要：

We present ESR results from Y1−xGdxBa2Cu3O7−δ with variable x content, from both sintered samples (2.10−4 ≤ x ≤ 1) and single crystals (x= 1 and 0.02), and compare them with previous results. Between 100 and 300k, the coupling of Gd3+ with conduction electrons is weak or moderate and does not reduce the relaxation time of Gd3+ ( 2.10−10s ≪ T1 ≤ 10−6s ). © 1990, Elsevier Science Publishers B.V.
