Kerr - June 8, 2016

              Today we discussed quite a few important concepts in the overall experiment.

Riad's Magnet will be running at 72 Volts and 400 Amps for the Molybdenum pucks and then a little higher for the Steel pucks corresponding to 2000 G in our area of interest

Our area of Interest, from the magnetic field graphs he gave us, shows a magnetic field around 1500 Gauss

This is crucial as we look to find a rare earth Iron alloy that saturates ideally near 1500 Gauss

We have decided maybe a few Alloys that saturate from 1000 G - 2000 G would suffice (I need to find these online ASAP)

               Other things I learned

• For many Target materials the relation between magnetization (observable) and Polarization (Quantity of interest) is not well known.
• Joe talked about a way to multiply the rotation in the Kerr effect by a repeating
• Temperature may affect Polarization
• Iron is most characterized when it comes to polarization and magnetization (8.4% Polarization)
• We are going to be using an Out-of-plane magnetization
• Slater-Pauling Relation?

Also, I want to be thinking about what I want to show at the GTS meeting next week. Tuesday 2.45 pm
