Abstract
A new system of observing and measuring magnetic domain is designed in this paper. The system includes three parts - the principal part of observing and measuring the magnetic domain, the crate controller and the computer used to control the whole system. The principal part consists of x-y scanner, z scanner, digital source meter, ion blower, optical microscope, and giant magnetic resistor (GMR) magnetic head. The GMR magnetic head in this system can be intact after a long-time running in the ordinary laboratory by taking some measures of eliminating electrostatic discharge (ESD). We successfully observed the magnetic domain written in a nanomagnetic material and measured the size of the magnetic domain by use of the new system. The system is very simple and inexpensive, and it has high resolution and signal-to-noise.
