I know we can create Gmr (giant magnetoresistance) films using PVD techniques but I was wondering if it would be possible to do so using something non-traditional let's say like mechanical alloying? wouldn't it be possible to make nm thin irregular flake particles of the individual elements and then mechanically alloy them? I know there is no control as such in a high-energy ball mill but I am thinking wouldn't at least some percent of powders form the required GMR structure? Do you guys have any suggestions to create such particles other than using the traditional thin film techniques?
yes, it is possible to create GMR materials using non-traditional methods such as mechanical alloying.
In theory, it is possible to create GMR materials using mechanical alloying. The process involves mixing the individual elements that make up the GMR material (such as Fe, Co, and Ni) in a ball mill and then milling them to form a homogeneous mixture. The resulting powder can then be compacted and annealed to form a GMR film.
However, creating GMR films using mechanical alloying is challenging, and the resulting films may not have the same properties as those created using traditional thin-film deposition techniques.
In terms of suggestions for creating GMR particles other than using traditional thin-film techniques, one possible approach is to use chemical synthesis techniques such as sol-gel processing or hydrothermal synthesis. These techniques can be used to synthesize nanoparticles of the individual elements that make up the GMR material, which can then be assembled into a GMR film using self-assembly or other techniques. However, it is important to note that these techniques also have their own limitations and challenges.
