For Pb(Fe0:5Nb0:5)O3 the $magnetization measurements up to 70 kOe were performed with the aim to estimate the antiferromagnetic (AFM) and superantiferromagnetic (SAF) contribution to $magnetization. Below TN the increase of$magnetization is attributed to a small part of Fe3+ ions in the SAF clusters. For high felds the suppression of the AFM and enhancement of the SAF susceptibility was observed. An infection point of the m(H) curves below the Néel point suggests the presence of a spin reorientation process connected with the AFM phase.
