Magnetic Measurement Facility readings of pucks, Steel () and Molybdenum --> media:LDGT01 Puck Measurements for MOKE 16-7-28.xlsx

This graph reads 6.33 Gauss/1 Amp. Note this is only the magnetic field at the surface of the Steel () puck.

Important INFO to note

• foil surface diameter across is 11 mm +-.5 mm
• Laser dot diameter through polarizer to foil surface is 2mm +-.5 mm

Excel Sheets for MMF data taken First, Data taken with original setup. Stage untouched since the 28th. Before stage was realigned in an attempt to be parallel with foil
