Article Synopsis
- * This study explores how the interaction between CoO and a ferromagnetic Co film, through a phenomenon called exchange bias, reveals changes that indicate the establishment of a "spinterface."
- * Specifically, the adsorption of carbon (C) and gallium (Ga) on CoO enhances its antiferromagnetic properties by redistributing charge, leading to increased blocking temperature, exchange bias fields, and coercivities in the Co layer.
Superconducting nanofilms are tunable systems that can host a 3D-2D dimensional crossover leading to the Berezinskii-Kosterlitz-Thouless (BKT) superconducting transition approaching the 2D regime. Reducing the dimensionality further, from 2D to quasi-1D superconducting nanostructures with disorder, can generate quantum and thermal phase slips (PS) of the order parameter. Both BKT and PS are complex phase-fluctuation phenomena of difficult experiments.

Orbital hybridization at the Co/C interface been has proved to strongly enhance the magnetic anisotropy of the cobalt layer, promoting such hybrid systems as appealing components for sensing and memory devices. Correspondingly, the same hybridization induces substantial variations in the ability of the Co/C interface to support spin-polarized currents and can bring out a spin-filtering effect. The knowledge of the effects at both sides allows for a better and more complete understanding of interfacial physics.
