Claim 1
Independent Claim
129 words
A ROLLED, SHEET-LIKE BODY OF A BODY-CENTERED CUBIC MAGNETIC MATERIAL CONSISTING ESSENTIALLY OF AT LEAST 92 PERCENT IRON, UP TO 5 PERCENT SILICON, UP TO 5 PERCENT MOLYBDENUM, AND UP TO 8 PERCENT ALUMINUM, AND HAVING A MAJORITY OF CONSTITUENT GRAINS THEREOF IN THE (100) (001) ORIENTATION TO PROVIDE TWO DIRECTIONS OF EASIEST MAGNETIZATION IN THE PLANE OF SAID SHEET-LIKE BODY, ONE OF SAID DIRECTIONS BEING PARALLEL TO THE ROLLING DIRECTION AND THE OTHER SAID DIRECTION SUBSTANTIALLY TRANSVERSE THERETO, SAID BODY FURTHER HAVING A MAJORITY OF THE MAGNETIC DOMAINS ALIGNED GENERALLY PARALLEL ONE OF SAID EASIEST DIRECTIONS OF MAGNETIZATIONS AND HAVING A MAGNETOSTRICTION OF FROM ABOUT -0.5 TO 1.0 WHEN SUBJECTED TO A MAGNETIC FIELD OF ABOUT 15.5 KILOGAUSSES APPLIED GENERALLY PARALLEL TO THE DIRECTION OF THE DOMAIN ALIGNMENT.
