Epitaxial double perovskite La2CoMnO6 thin films were grown on top of (001)-STO oriented substrates by a polymer-assisted deposition chemical solution approach. Confirmation of the achievement of full Co/Mn cationic ordering was found by scanning transmission electron microscopy (STEM) measurements; EELS …
Disorder and spatial localization due to thickness reduction allow generating a metal-insulator transition in semimetallic SrIrO3 thin films. Below about 3nm films are insulating with hysteretic I-V curves indicative of resistive switching behavior at room temperature. Current maps allow demonstrating …
Trapping and electrical characterization of single core/shell iron-based nanoparticles in self-aligned nanogaps
We report on the fabrication and measurements of platinum-self-aligned nanogap devices containing cubed iron (core)/iron oxide (shell) nanoparticles. See more here
The cluster gun technique can go beyond fabrication of single particles into controlled and reproducible self-assembly of NPs as they form. See more here.
The magnetic properties of the ferromagnetic insulating La2Ni1−xMn1+xO6 double perovskite are studied. It is found that Ni/Mn stoichiometric samples always exhibit values of TC and MS far from the optimum ones. In contrast, Ni-deficient samples show excellent magnetic properties. The …
Nanoscale mechanical control of surface electrical properties of manganite films with magnetic nanoparticles
Mechanical control of electrical properties in complex heterostructures, consisting of magnetic FeOx nanoparticles on top of manganite films, is achieved using atomic force microscope (AFM) based methods. See more here
In our last paper published in Scientific Reports we demonstrate that a single ferromagnetic insulating barrier with strong magnetocrystalline anisotropy is sufficient for realizing sensor and memory functionalities in a tunneling device based on TAMR. Read the full paper here.
