Title: MTJ with ferrimagnets as electrodes
Post by: leslie on June 18, 2011, 14:35

Dear Colleagues,

Is it possible to carry on transport calculation with ATK 2011.2 for the stacking trilayer device like Fe-MgO-Fe, but using compensated ferrimagnets as electrodes instead of ferromagnets? Will this induce any unexpected mistake?

Thanks,

leslie

Of course, you can. But before studying the tracking trilayer device with the compensated ferrimagnets, one had better do the bulk calculations to check whether the magnetic ground states of the compensated ferrimagnetic electrode are predicted well or not using the LDA(or LDA+U).

Dear zh,

Thanks very much.

By compensated ferromagnets, do you mean compensated ferrimagnets.....?  ;)

Sorry, there is a typo in my last reply. Now it is updated.
