摘要：

We have applied a developed HTS de SQUID based magnetic microscope far study of the magnetic properties of ultrathin Ni films. A magnetic moment sensitivity close to 10(-15) A.m(2)/Hz(1/2) has been obtained at 77 K. The space resolution was determined at level of 100 mu m by the separation between the SQUID and the studied film surface. One-domain structure, in-plane orientation of magnetic moment and ferromagnetic-like ordering in 26 Angstrom thick film were found. An absolute value of the film magnetic moment has been estimated.
