摘要：

A technique for quantitative determination of the ultrathin films volume magnetization in the in-plane magnetizing field up to 10(4) A/m has been developed. This technique uses a scanning SQUID microscope with the YBCO thin film bicrystal de SQUID and allows us also to reveal the orientation of the sample magnetization. A spatial resolution of about 100 mu m and a field of view of 8 x 8 mm(2) have been obtained. The resolution in terms of the magnetic moment of the studied film was close to 10(-15) Am-2/Hz(1/2) at 1 Hz. (C) 1998 Elsevier Science Ltd. All rights reserved.
