Abstract
The results of 155Gd Mossbauer studies (above 1.5K) of the oxides, Bi3.5Gd0.5Ca3Sr3Cu4O y and Bi2Sr2Ca1-x Gdx Cu2Oy (x=0.25 and 0.5) are reported. The observed electric quadrupolar split resonance patterns suggest that Gd ions prefer to occupy Ca site in both series. The spectral features give evidence for paramagnetic relaxation of isolated Gd ions at low temperatures.
