| Popis: | Magnetic properties of amorphous ferromagnetic wires serving as a magnetic flux guide for the high- T c SQUID microscope are investigated. A mathematical model of a flux guide operation was developed on the base of integral equation methods. It is shown that when the flux guide is used in combination with the SQUID the integral of magnetic potential along the flux guide is the main measured value. Experimental results received with the use of the scanning high- T c SQUID microscope for liquid-nitrogen cooled samples are in good agreement with the proposed model. |
