Abstract
Nanobridges are fabricated from lanthanum-strontium manganite deposited on Si3N4 membranes perforated by a focused ion beam. The magnetoresistance is approximate to 9% in fields of similar to 1 kOe. Nonlinearity of the curren t-voltage characteristic of the bridges is observed, and it is found that t he maximum of the resistance is shifted to lower temperatures from that of a control film sample of composition La0.8Sr0.2MnO3.
