Abstract

Método de fabricación de cuerpos de materiales ferromagnéticos que tienen una estructura cristalina no cúbica, cuyos monocristales muestran un plano de magnetización preferido, caracterizado por el hecho de que un polvo del material ferromagnético cuyas partículas tiene un cierto grado de libertad de movimiento relativo una con respecto a la otra, es alineado en un campo magnético y luego unificado.
