DOI: 10.1063/1.4979586
Abstract: We present a systematical study on the evolution of antiphase boundary (APB) densities in Fe3O4 films, which were prepared by pulsed laser deposition and post annealing at different temperatures. By measuring the electron-phonon coupling parameter… read more here.

Abstract: The magnetic and transport properties of magnetite (Fe3O4) films grown on isostructural substrates (MgAl2O4, MgGa2O4, and CoGa2O4), with varying degrees of lattice mismatches (3.8%, −1.4%, and −0.8%, respectively), have been investigated. A significant reduction in… read more here.

DOI: 10.7567/1882-0786/aaf285
Abstract: We investigated the electrical properties of Fe3O4 films grown on MgO (001) substrates by pulsed-laser deposition for use as high-temperature resistors. By systematically examining the thickness-dependent resistivity and magnetoresistance, we found that a film thickness… read more here.
