Growth and properties of pulsed laser deposited Fe3O4/La0.7Ca0.3MnO3 bilayers

Low field magnetoresistance in La0.67Ca0.33MnO3 and Co3O4 combined system

“…Very recently, enhanced MR properties have been observed in some ferromagnet/insulator type two phase manganites-based composites, such as LSMO/CeO 2 [8], LCMO/STO [9], LSMO/glass [10], LSMO/NiO [11], LBMO/YSZ [12] and bilayers of LCMO with Fe 3 O 4 [13].…”

Enhanced low field magnetoresistance in La0.7Sr0.3MnO3/TiO2composite

“…Very recently, it was reported that introduction of a second phase, usually a non-magnetic or an antiferromagnetic inorganic insulator, into the ferromagnetic manganites matrix leads to an improved MR [13][14][15][16]. Some attempts have been made to study this enhancement in MR through the formation of composites of these manganites with inorganic insulators [13][14][15][16][17][18][19][20][21]. In addition to this, manganitepolymer composites have also been studied [11].…”

Magnetotransport properties of Fe3O4–La0.7Sr0.3MnO3junctions

“…The distinctively different field dependence of the magnetoresistance in these two types of heterostructures might be tentatively attributed to the different barrier materials. Related work on Fe 3 O 4 /La 0.7 Ca 0.3 MnO 3 bilayers was reported in [15] albeit without addressing the field dependence of the bilayer magnetoresistance.…”
