Application Notes
The end result in this case is that the mean free path length of the conduction electrons is fairly short,
resulting in a relatively high electrical resistance.
If an external magnetic field of sufficient magnitude is applied to this GMR material, it will overcome
the antiferromagnet coupling of the magnetizations between the two magnetic layers . At this point all
the electrons in both films will have the same spin . It will then become easier for the electrons two
move between the layers:
Spin States of the Magnetic Layers are the same;
Electrons Travel More Readily Through Entire Stack of GMR Material.
Average Mean Free Path of the Electrons is Long

Note that the mean free path length of the electrons has now increased . This results in an overall lower
electrical resistance for the GMR material . The change in resistivity of the material is shown on the
path length diagram below:
