Special Issue Information
Dear Colleagues,
Spintronics is a new technology used for storing, displaying, and processing information based on changes in the electronic properties of magnetic field materials. The magnetization alignment can influence asymmetric interaction with various biological systems and, furthermore, can be used for spintronic applications by utilizing quantum-mechanical effects.
Recently, parallel efforts to induce spin selective charge imbalance have attracted enormous attention in the interdisciplinary community. There is the belief that electronic spin couples its degree of freedom with one of the most intriguing asymmetries in nature, chirality. Chirality corresponds to handedness, such that chiral objects are mirror replicas but cannot be superimposed over each other. Interestingly, moving electrons with specific spin also follow chiral paths due to their asymmetric momentum. This enables the chiral system to couple with a spin degree of freedom of an electron, and allows specific spin to travel through this chiral system, and vice versa for the opposite spin. In the past, many systems were developed to create spin imbalance, such as spin filtering or spin polarized current. For example, recently, in supramolecular helical structures, 50 to 60% spin polarization has been observed, where one can easily control the helicity in order to enable spin polarization. Beyond the molecular measurement, significant effort has also been taken to make real spin valves using these systems. Magnetoresistance devices have been modified, where the soft ferromagnetic layer of the prototype device is replaced with a helical system, enabling spin filtering up to 10%. Although there are several applications of this effect, it is important to realize that a more basic understanding of the phenomenon is required.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Magnetochemistry is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
