For CPP GMR spin valve fabrication, two methods are designed by using e-beam lithography (EBL). These methods are no etching processes. One is making a nano hole by two EBL processes and deposit two SiO2 layers to isolate the upper and lower conductor. Another is using PMMA to be a isolator, and developing a gradient lithography method to make a nano contact. Another purpose is to study GMR sensor types and applications. A commercial angular GMR sensor is used in a complex 2-D magnetic field of the BLDC motor. Only one 2-D GMR sensor is needed in dynamic BLDC motor magnetic field measurement to analysis the rotor position, permanent-magnet field and stator q-axis component current at the different time phase and the torque can be calculated. 許仁華 2013 學位論文 ; thesis 124 zh-TW |
