Abstract

PURPOSE: To provide a transducer good in the sensitivity, temperature characteristics and anticorrosivity by heat treatment at 200∼450°C a of troidal core molded selecting at least one from Si, B, P and C and at least one from Si, B, P and C and at least one from Fe, Co and Ni.
CONSTITUTION: An amorphous magnetic material as given by the formula of MaYb comprising a component Y containing at least one kind of Si, B, P and C and M at least one kind of Fe, Co and Ni is used to prepare a troidal core, where a and b are symbols indicating the ratio of the atomic number. The relationship between a and b is specified at a+b; 100%, 10≤b≤30. To achieve this, the mixture is molded into the shape of the troidal core and undergoes a heat treatment at 200∼450°C in the gas containing one or more kinds of N2, H2 and O2 or under vacuum. Then, it is cooled applying magnetism vertical to the troidal face. The use of the vertical magnetic field serves to improve the characteristics.
