Help with this template Comments: edit – history – watch – refresh Although I cannot add any correction to this article, I can asure you that there is in fact at least one theory wich explains this effect. I strongly suggest that you look for the credible guidance on this subject so that you can improve the quality of the information provided. The only - yet very serious - problem about the internet as source of information is that the huge quantity of information is rarely believable. I truly wish that Wikipedia suceeds as a credible source of knowledge and remain as the main reference of Web Encyclopedias. Greatings, Ivo Leite (physics' student)

The theory about why this works may be understood at the current point in time (Due to what is written on the Oak Ridge web site), and needs an expert to review.

I don't think it's understood yet. One of my team members works directly with the theory group at ORNL. They have some theories, and have been testing them and publishing papers, but colossal magnetoresistance still isn't a completely understood phenomenon. SeanAhern 01:11, 21 February 2007 (UTC)

The main features of CMR are understood within the double exchange mechanism, plus the phase separation phenomenon. The latter is not completely understood yet, at least in a quantitative way. But it's quite incorrect to say that "no physical theories" explain this phenomenon. --130.251.188.1 13:53, 20 March 2007 (UTC)
