Abstract

Solid solutions (Ho_xIn_1-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.
