The Stoner-Wohlfarth Model describes the hysteresis of single domain ferromagnets when an electric field is applied at some angle θ from the easy axis. An interactive python code to quantitatively simulate this hysteresis is available from the depository above.

The reciprocal lattice of a crystal represents the Fourier transform of real space lattice and is used to calculate the expected diffraction pattern from X-ray or neutron diffraction. Operations in real space and reciprocal space have an inverse relationship (increasing length in real space decreases it in reciprocal space) which can oftentimes be difficult to visualize. An interactive python code comparing real space and reciprocal space for arbitrary angles and lengths is available at the depository above.

The lab has received new deposition and characterization equipment courtesy of IMRA America! Donated to our lab was:

• 3 Thermionics PLD-PVD deposition chambers.
• 1 thermal evaporator and power supply.
• A Van der Pauw and Hall effect measurement system.
• Solar performance testing station.
• A plethora of deposition materials in 1 -2 in targets.
• 3 sputtering guns and power supplies.

We are already putting these new facilities to use with the growth of oxide nanowires and chalcogenide thin films. We are still setting up the other equipment but are excited by all of the new possibilities. Thanks IMRA!

The lab welcomes:

Thomas Kratofil

Jesse Newton

Andrew Williamson

Jiawei Zhang

These students are already learning how to safely work in a PLD lab, building laser enclosures, making targets and soon to be depositing materials!

Welcome guys! Be safe, have fun and and may the oxygen octahedral be with you in all your endeavors.
