Research Interests

Magnetic Recording Technology for Hard Disk Drives and Digital Tape Recording

Magnetic recording technology has been advancing in dramatically rapid pace over the past decade during which we have made some important contributions. At present, our research includes:

  1. Development of novel recording mechanisms that enables area storage density exceeding 1 Tbits/in^2 for hard disk drive applications;
  2. Development of novel perpendicular thin film media microstructures that capable of high area density applications;

The research is supported by DSSC and its industrial sponsors.

Innovative Designs of Magnetic Random Access Memory (MRAM)

MRAM has the potential to replace SRAM, DRAM, FLASH, and even a small disk drive to be the universal memory for computer data storage, enabling an entire computer system to be made on a single chip. Our research focuses on novel MRAM designs that offer robust and repeatable magnetic switching characteristic, low operation power capability, and sufficient thermal-magnetic stability. Micromagnetic modeling on computers is utilized to aid the design process and the devices are fabricated using the state-of-the-art e-beam and optical lithographic fabrication technology. Our collaborators include the Naval Research Laboratory and Nonvolatile Electronics Corporation. This research is current funded by the Office of Naval Research, Pittsburgh Digital Green House, STMicroelectronics, and DSSC.

Understanding Noise in Nano-Magnetic Systems

Thermally excited magnetization precession and spin current induced chaotic spin waves are two important causes of magnetic noise in advanced nano-scale magnetic sensors. We perform both theoretical analysis and experimental measurements to obtain a good understanding of the noise and the corresponding underlying physics. This research is supported by Seagate Technology and DSSC.
