Special Issue Information

Dear Colleagues,

Magneto-related effects in chemistry is a field in rapid growth and expansion, involving both fundamental and applicative aspects. This Special Issue focuses in particular, but not exclusively, on magnetic field effects combined with electric field effects, with particular emphasis on electrochemical-based systems. The effect of magnetic fields on the potential and current quantities characteristic of an electrochemical cell are typical observables worth measuring, as are the entangled effects of chiral systems (chiral surfaces) and the observation of spin-related effects. The relationship, also based on purely theoretical considerations, between spin and magnetic effects and a material’s electronic structure at the molecular level is also of great interest. Original papers as well as reviews on these subjects are welcome.

Surface Chirality in Rotational Magnetoelectrodeposition of Copper Films
Magnetochemistry 2019, 5(3), 53; https://doi.org/10.3390/magnetochemistry5030053 - 12 Sep 2019
Abstract
Chiral surface formation was investigated in rotational magnetoelectrodeposition (RMED) of copper films, where an electrochemical cell was rotated in magnetic fields. The RMED was conducted with clockwise or anticlockwise rotation in the magnetic fields parallel or antiparallel to the ionic currents. The rotational [...] Read more.
Chiral surface formation was investigated in rotational magnetoelectrodeposition (RMED) of copper films, where an electrochemical cell was rotated in magnetic fields. The RMED was conducted with clockwise or anticlockwise rotation in the magnetic fields parallel or antiparallel to the ionic currents. The rotational frequencies were 0.5–6 Hz, and the magnetic fields were 2–5 T. The chiral behaviors are divided into four types: type I has chirality depending on the magnetic field polarity, type II has chirality depending on the rotational direction, and type III has chirality depending on both directions. Type IV represents chiral symmetry breaking, where the RMED films exhibit only L activity in any magnetic field polarity and rotational direction. Full article

Nano-structured Dilute Magnetic Semiconductors for efficient spintronics at room temperature

Abstract: Silicon industry requires novel materials to cope with ever-increase information density [1-2]. Spin-based electronics pose as strong alternative due to advantages originating from quantum mechanical properties [3]. However, major limitation for semiconductor spintronic devices is to develop suitable materials that will effectively allow spin-polarized carriers to be injected, transported, and manipulated [4]. In this way, dilute magnetic semiconductor (DMS) with non-significant doping with transition metal ions to induce ferromagnetism [5]. Recent developments in academia and industries showed that DMS holds superior control over charge and the spin degrees of freedom [6-8]. Instead of much effort, although significant efforts have been carried out to achieve DMS with ferromagnetic properties above room temperature for the commercial applications and however, still much improvement is needed as most of the materials are not suitable for practical applications as their Curie temperatures are quite low.

However, some theoretical prediction shows that room temperature ferromagnetism is possible in DMS[9] as evident from Co, Mn, Ni, Cr etc. doped ZnO, SnO2 and TiO2 semiconducting oxides [10]. This review highlights the doping effects of transition metal ions on the structure, transport, defects and diluted magnetic properties of various host oxides semiconductors. We will be summarizing a few possible origins of the magnetic properties that could explain magnetism in DMS materials whether due to spin interaction or defects.

Keywords: Information density; Dilute magnetic semiconductor; Magnetism; Curie temperature.
