Abstract (in Japanese) (See Japanese page) 
(in English) We investigated magnetic tunnel junctions (MTJs) La0.7Sr0.3MnO3(LSMO)/LaTiO3/La2NiMnO6(LNMO)/Cr/Au which were fabricated on SrTiO3 substrates to examine spin-filtering effect through the ferromagnetic insulator LNMO by the measurement of tunnel magnetoresistance (TMR). The MTJ showed TMR ratio of about 19 % at 50 K and about 10 % at 110 K accompanied by the change of magnetization configuration of LSMO and LNMO from parallel to antiparallel. The spin polarization of the tunnel current through the LNMO barrier was estimated to be about 9 % at 50 K and about 4 % at 110 K.
