Abstract:
An investigation of the n = 1, 2, 3 and infinity members of the (La, Sr)(n+1)MnnO3n+1 or the (SrO)(La1-xSrxMnO3)(n) family has shown the dependence of the I-M transition temperature and the magnitude of magnetoresistance (MR) on dimensionality, MR decreases as dimensionality increases from 2 to 3.
