Investigation on Spin Dependent Transport Properties of Core-Shell Structural Fe(3)O(4)/ZnS Nanocomposites for Spintronic Application

The core-shell structural Fe(3)O(4)/ZnS nanocomposites with controllable shell thickness were well-fabricated via seed-mediate growth method. Structural and morphological characterizations reveal the direct deposition of crystalline II-VI compound semiconductor ZnS shell layer on Fe(3)O(4) particles...

description The core-shell structural Fe(3)O(4)/ZnS nanocomposites with controllable shell thickness were well-fabricated via seed-mediate growth method. Structural and morphological characterizations reveal the direct deposition of crystalline II-VI compound semiconductor ZnS shell layer on Fe(3)O(4) particles. Spin dependent electrical transport is studied on Fe(3)O(4)/ZnS nanocomposites with different shell thickness, and a large magnetoresistance (MR) ratio is observed under the magnetic field of 1.0 T at room temperature and 100 K for the compacted sample by Fe(3)O(4)/ZnS nanocomposites, which is 50% larger than that of sample with pure Fe(3)O(4) particles, indicating that the enhanced MR is contributed from the spin injection between Fe(3)O(4) and ZnS layer.
