«Aside from the large magnetoresistance of this compound, other important advantages are its non-toxic composition and the fact that it can be used even at higher temperatures.» (sciencedaily.com)
But in particular, researchers in the Cava lab noticed that five materials with extreme magnetoresistance yet very different structures and chemical make - up all share the same characteristics when their resistance - temperature - applied - magnetic - field diagrams are measured.

And researchers in Japan raised it to 600 % in 2002 with the discovery of materials that carry out something called tunnel magnetoresistance. (sciencemag.org)
