Special Issue Information

Dear Colleagues,

I am pleased to share the upcoming Special Issue of Nanomaterials, “Nanoscale Spintronics and Magnetism: From Fundamentals to Devices”.

I, therefore, invite you to submit your research work, in the form of a full paper, communication, or review.

The aim and purpose of this issue is to present cutting-edge research on topics such as nanoelectronics, nanosensors, and devices.

A small introduction follows to explain the general topic: Nanoscale Spintronics and Magnetism: From Fundamentals to Devices.

In recent years, more and more researchers have focused on spintronics, exploring next-generation materials and/or nanoelectronic devices that rely on electron spin and are characterized by reduced energy consumption, increased high-speed, high-density memory, etc. In short, materials/devices take advantage of the degree of spin freedom of electrons and/or holes and the interaction with the orbital moments.

On the other hand, the field of molecular magnetism is rapidly evolving towards the use of magnetic molecules and magnetic nanomaterials in the field of molecular spintronics, quantum technology, etc. Magnetic materials can become a cornerstone of spintronics through the control of spin configurations. Molecular materials, single-molecule magnets, MOFs, 2D materials, and even the isolation of hybrids from single-molecule magnets and spin crossover nanoparticles are some examples that have attractive properties and functions in spintronics.

We demonstrate tunable ferrimagnetic properties in both bulk and thin film ferrimagnetic DyCo3 compatible with the hosting of topological magnetic chiral textures, namely skyrmions suitable for integration into spintronic applications with classic, neuromorphic and quantum functionalities. The bulk samples were prepared by arc-melting of stoichiometric mixtures under purified argon atmosphere and the thin films by Ultra-High-Vacuum magnetron sputtering from a stoichiometric target. Magnetometry allows us to extract the main magnetic properties of bulk and thin films: the saturation magnetization, the magnetic anisotropy and their variation with temperature. These results are successfully complemented by band structure ab initio DFT calculations. Based on the critical magnetic parameters extracted from experiments, we performed micromagnetic simulations that reveal the skyrmionic potential of our samples in both continuous thin film and nano-patterned architectures.

The magnetic toroidal dipole moment, which is induced by a vortex-type spin texture, manifests itself in parity-breaking physical phenomena, such as a linear magnetoelectric effect and nonreciprocal transport. We elucidate that a staggered alignment of the magnetic toroidal dipole can give rise to spontaneous magnetization even under antiferromagnetic structures. We demonstrate the emergence of uniform magnetization by considering the collinear antiferromagnetic structure with the staggered magnetic toroidal dipole moment on a bilayer zigzag chain. Based on the model calculations, we show that the interplay between the collinear antiferromagnetic mean field and relativistic spin-orbit coupling plays an important role in inducing the magnetization.
