Wombat3-16Dec08

Jacob Jones and Abhijit Pramanick, from the University of Florida, carried out in situ real-time experiments on PZT (lead zirconate titanate ferroelectric), which was subjected to a cycling electric field, switching at rates of 1Hz to 1kHz. The data were acquired stroboscopically, with up to 64 time bins measured for each period. The changes in diffraction peak with field are very subtle and Wombat's high flux is indispensable in measuring them.

The smallest sample so far measured on Wombat was a 150 nm thick FePt₃ multilayer sample (by Frank Klose and Thomas Saerbeck, Bragg Institute). This corresponds to 220 micrograms of material. The image below shows the 200 reflection of FePt₃.
