摘要：

Fe-57 absorption and Co-57 emission Mossbauer measurements show that the Fe and Co atoms mainly substitute for Cu at Cu1 chain sites of YBa2Cu3O7. On the other hand, in YBa2Cu3O6 the Fe and Co atoms occupy also Cu2 plane sites indicating an antiferromagnetic long-range order. Direction of magnetic moment of Fe at Cu2 site is determined to be normal to the c-axis.
