Solid solutions (HoxIn1-x)1.9Sn 0.1O3 with x=0-0.3 were synthesized to employ as dispersion matrix for oleic acid coated Fe3O4 nanocrystals (NCs). The x=0.05 matrix exhibited a resistance minimum at a non-zero temperature in each temperature dependent resistivity with magnetic fields of 0 and 1T, and a negative magnetoresistance. The sample of oleic acid coated Fe3O4 NCs dispersed in the x=0.05 matrix showed enhanced spontaneous magnetization as the factor of ≈1.3 relative to as-synthesized oleic acid coated Fe3O4 NCs.
