Abstract

Method for manufacturing laminated materials, characterized in that it comprises the steps of constructing a laminate consisting of layers of a soft magnetic metal separated by at least one layer of an inorganic material of a type which, when heated, adheres to the soft magnetic metal and will result in an inorganic layer whose electrical resistivity is greater than that of the soft magnetic metal; and heating the laminate to result in a structure consisting of layers of soft magnetic metal separated and adhered to the inorganic material whose electrical resistivity is greater than that of the soft magnetic metal.
