Electrical performance and reliability of tunnel magnetoresistance heads for 100-Gb/in/sup 2/ application
Tunnel magnetoresistance (TuMR) heads are attractive candidates for future high-density recording. To achieve the high areal density, it is necessary for TuMR heads to get lower resistance and higherExpand

Low-frequency noise analysis of TMR heads
1/f noise as time traces of the fluctuation and low-frequency noise (pulse noise) were observed in TMR heads. These were then related to the quality of the oxide layer in the TMR heads.
