Our research focuses on the fabrication and invention of magnetoresistive sensor and considering various approaches – sensor structures, sensing materials, pattern design and bio-applications. Through our research, we will develop emerging materials and design of high sensitivity and high resolution magnetic resistive sensor using by planar hall effect.
Commonly, we use DC sputtering system in order to deposit sensor materials. By using ferromagnet (NiFe) and antiferromagnet (IrMn), we fabricates sensor structure such as spin-valve, trilayer, etc. In order to improve sensor properties, we try to make 3d structure sensor and filter type sensor.
