Vaneet Sharma, Maria R. Hossu, Woo Ho Lee, Ali R. Koymen, and Shashank Priya This letter reports the giant piezoresistance phenomenon in Nb[sub 2]O[sub 5] modified La[sub 0.8]Sr[sub 0.2]MnO[sub 3] (LSMO) polycrystalline ceramics. LSMO modified with 2 mol % Nb exhibited ~2% change in resistivity at 19.2 MPa pressure as compared to 0.5% for the pure LSMO. A dramatic improve ... [Appl. Phys.
