Summary :

An application of composition graded Gd-Fe amorphous films to a magnetic sensor was studied. The composition graded Gd-Fe amorphous films were prepared by means of a coevaporation technique. The Gd-Fe films were evaporated on the Sio films which were deposited previously on glass substrates, then the Gd-Fe films were overlaid with SiO films. The ferromagnetic domain patterns on the films were examined by means of polar Kerr effect. A magnetic sensor measuring the magnetic fields near the surfaces of specimens was designed using the Gd-Fe film. The magnetic field was determined by measuring the area in which magnetization was inverted by the field. It was demonstrated that the magnetic sensor consist of the Gb-Fe film measured the normal magnetic fields near the specimen less that 1 µm from the surface in the range of 50 to 500 Oe.
