I'm back. I tried changing the strip thickness, so they cover the entirety of the film (in the z direction), and I also added boundary conditions between the FM and conductive areas (both contacts and strips). This resulted in the current flowing properly through the strips, but in the magnetic...
I'm not exactly sure what you mean by only half of the electrode, but here is a basic description of how I calculate j (notice that the blue and grey cells have a spatially variant conductivity, so j cannot be homogenous in that region):
1. First of all, I define an initial approximation for...
I did test it for a ferromagnetic film with no strips added, and the current seemed to behave the way it should. Do you know what bc I should include? I solve Eq. 6 in every cell except for those that are subject to bc, and then I impose them. If I can't do that, then how can I account for the...
Hi, Tom!
First of all, thank you for answering.
You are absolutely correct, the whole point of these high-conductivity regions is that they are supposed to shunt the current, so that it "jumps" to the next strip. So the current should indeed flow at a 45 degree angle (relative to the X axis) in...
Hi everyone! First time posting here, so I apologize in advance for any bad formatting. I am working on a mathematical model of an anisotropic magnetoresistive sensor. The central part of such a device is a Wheatstone bridge that consists of four current-carrying ferromagnetic (FM) films, the...
