Abstract

Un método de preparar un núcleo ferromagnético para una memoria o un elemento de circuito que tiene un lazo de histéresis substancialmente rectangular, caracterizado porque una mezcla de óxidos que tiene una composición o compuestos que forman óxidos durante el calentamiento, es fusionada si fuera deseable después de una pre- fusión, a aproximadamente 1000ºC hasta aproximadamente 1300º en una atmósfera no reductora.
