High field magnetization of GdB5 is investigated up to 550 kOe. The saturationmagnetization of 7 : 0.5 7t. is o btained around 490 k0e at 1.3 K and the system canbe regarded as a typical cubic antiferromagnet with the nearest neighbor exchangeenergy J./ k of - 0.78 f 0.02 K. Beside the standard antiferromagnetic magnetization,two small anomalous step-magnetizations are found near the saturation field H..They are explained by the local spin flip of the disordered Gd located at the B5 clustersite. Two kinds of the disordered states, Type-I and Type-II, are proposed corresponding to two steps. The disordered Gd spin couples with the surrounding hostspins with the antiferromagnetic exchange energy J'/ k of - I.2K and - 1.3 K forType-I and Type-II, respectively.
