| Abstract | We report the observation of a large magnetoresistance ~83%! at low magnetic fields of tens of Oe at 4.2 K in the epitaxial trilayer junction structure, La 0.67Sr0.33MnO3/SrTiO3/La0.67Sr0.33MnO3. The spin-polarization parameter of the manganite has been determined from the magnetoresistance value. The switching fields of the two magnetic layers were designed by using the magnetic shape anisotropy. By limiting the sweeping field in a low field range ~;100 Oe!, we have achieved bistable resistive states at zero field, which is of potential interest for magnetoelectronic applications. ©1997 American Institute of Physics. @S0021-8979 ~97!73108-6# |
