Solid solutions (Ho x In 1− x ) 1.9 Sn 0.1 O 3 with x = 0–0.3 were synthesized to employ as dispersion matrix for oleic acid coated Fe 3 O 4 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 1 T, and a negative magnetoresistance. The sample of oleic acid coated Fe 3 O 4 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 Fe 3 O 4 NCs.
