In this letter we report on the growth of thick films of magnetoresist
ive La2/3Sr1/3MnO3 films using a spray printing technique. The as-prep
ared films display a room-temperature magnetoresistance of 0.0012%/Oe
in the 1 kOe field region. We will show that this field sensitivity is
high enough to fabricate devices which, operated under a bias magneti
c field, can be used as a sensitive and low-cost magnetic sensors. (C)
