The different
« on: February 22, 2020, 10:20 »
Hi Sir,

I am very confused. What is the different or relation between magnetic configurations (like one is magnetized while other is non-magnetic) and conventional parallel/anti-parallel  magnetic configurations of GMR devices ?

magnetized while other is non-magnetic

Materials can be magnetic or non-magnetic at particular temperatures, e.g., Fe is ferromagnetic below the Curie temperature, and paramagnetic above it. There are many different magnetic configurations, antiferromagnetic, ferrimagnetic and so on. You may consult some text book on that.   

) and conventional parallel/anti-parallel  magnetic configurations of GMR devices ?

That is just the same magnetic material (used for metal electrodes) with 2 different relative orientations (parallel / aniparallel) of magnetization vector in the 2 magnetic electrodes.

Thank you for the explanation. Could you suggest me or share the link of the textbook that i can refer to.
