Four-Year College Faculty-Student Team Fellowships Program

During the summer of 2005,

Prof. Yung Huh and student Robert Vaselaar from South Dakota State University (Brookings, SD) and Prof. Hector Mireles and students Adam Attig and Anital Hoempke from California State Polytechnic University (Pomona, CA) have joined the MRSEC research team.

Prof. Huh is inserting a
ferromagnetic thin film into SQUID.

“The research project is to study the pulsed laser deposited dilute magnetic semiconductors to understand the origin of magnetism in the oxide system, working closely with Professor David Sellmyer and postdoctoral fellow Jun Zhang. The research facility includes Pulsed Laser Deposition (PLD) system, Super-conducting Quantum Interference Device (SQUID), X-Ray Diffractometer (XRD), Atomic Force Microscope (AFM), Scanning Electron Microscope (SEM), and Rapid Thermal Annealer (RTA).”

During the summer of 2005, Anital Hoemke and Adam Attig prepared and investigated L10-ordered FePt thin films. By analyzing X-Ray Diffraction (XRD) 2-theta scans, they determined new sample-preparation parameters to create the (001)-textured L10-phase. They prepared samples in an argon ion sputtering chamber and annealed them in a rapid thermal annealer. The magnetic response of the textured L10 phase was established by Alternating Gradient Field Magnetometry (AGFM) and SQUID magnetometry. Successfully-prepared samples exhibited perpendicular magnetic anisotropy.

Anital and Adam are both physics undergraduates at Cal Poly Pomona, where they study magnetic domains using Kerr Microscopy in the lab of Dr. Hector Mireles.
