We are currently adding magnetic domain imaging to our MOKE magnetometer and we would like to remove laser speckle. What is the best way to do this?

We're running a 635 nm HeNe laser and are concerned about speckle severely impacting the quality of our domain images. I've heard about using a rotating plastic or glass disk, but has anyone had...

What's an easy way to average several magnetic hysteresis loops?

I'm using Origin to average 10 magnetic hysteresis loops, but because the center of the loop has multiple y values for each x (for the two legs of the loop) the averaging is coming out really...

How can one model an antiferromagnetic layer in the OOMMF 3D solver?

I'm familiar with how to model a layered structure using the atlas commands. I've been using the 6 neighbor energy term to model the exchange interaction, but I would now like to add an...

Strange shift in MOKE hysteresis loop

Hi everyone. Our group is currently building a magneto-optical Kerr effect (MOKE) magnetometer to study magnetic thin films. We're calibrating the system by comparing our MOKE measurements to VSM...
