Abstract

We report on detailed transprort measurements of single crystalline La(1-x)Sr(x)MnO(3) (x<=0.2). We have found a giantpositive magnetoresistance in the compositions range between 0.1<=x<=0.125 and give an explaination in terms of orbital ordering due to the interplay between superexchange interactions and Jahn-Teller distortions.
