MAGNETO RESISTANCE DEVICE MANUFACTURING METHOD FOR IMPROVING THE IMPEDANCE CHARACTERISTIC OF A GIANT MAGNETO AND MAGNETO RESISTANCE DEVICE THEREOF

摘要

PURPOSE: A magneto resistance device manufacturing method for improving the impedance characteristic of a giant magneto and magneto resistance device thereof are provided to use a magnetic sensor for a detailed magnetic field and information record medium by improving the impedance characteristic of a giant magneto.;CONSTITUTION: A magneto resistance device is manufactured by ion radiation energy. A frequency is allowed from one mega hertz to ten mega hertz. The ion radiation energy is increased from fifty kilovolts to one hundred kilovolts according to the change of the applied magnetic field. The sensitivity of the magneto resistance device is increased according to the increase of the ion radiation energy. The maximum sensitivity is appeared in five mega hertz. The sensitivity of the magneto resistance device is reduced in case the frequency is over than the five mega hertz.;COPYRIGHT KIPO 2012
