Title: Device and method for evaluating wide-range magnetizm of in-plane direction magnetized substance
Inventor: AKAHA KOICHI
IPC: G01N27/72
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To improve evaluation accuracy, by symmetrically arranging mechanical systems which respectively generate magnetic field to combine mirror symmetric magnetic field, and detecting with Kerr effect magnetism which has magnetization direction parallel to a reference plane near a mirror and is on the surface of a magnetic substance to be evaluated. SOLUTION: First and second mechanical systems respectively form magnetic fields, both magnetic force groups are symmetric in relation to a reference plane S, and lines of magnetic force on the reference plane S is approximately linear on a local reference plane. A magnetic disk 42 of an evaluated magnetic substance is placed on a transferring means 41, and magnetization direction of the position for its magnetic thin film is matched with the reference plane S to be coincident to the local reference plane. Providing magnetic field for the local reference plane causes magnetic field to occur on the magnetic thin film.  Laser light is collected on the magnetic thin film through an input-side polarizing element 27 and an input-side optical path 31, and its reflected light is entered into a light receiving element through an output-side optical path 32 and an output-side polarizing element 29. Using Kerr effect allows magnetic field strength on the magnetic thin film to be derived based on the polarization angle, and therefore real-time inspection can be performed.
