Dear Colleagues,

The nonlinear class of materials is broad and not limited to such classical representatives as ferroelectrics and ferromagnetics. At the present time, many works are dedicated to the search for new materials with nonlinear properties, and this research field has become increasingly attractive.

The nonlinear properties of materials are expressed differently depending on the fabrication technology. For example, in thin-film materials, nonlinear properties can be more distinct than bulk ceramic materials or vice versa. Nonlinear organic dielectrics should now also be recognized as a separate prospective research direction. Hence, technological aspects are the significant issue.

The nonlinearity of a material’s properties can be observed under a wide range of external factors, such as electric, magnetic, mechanical, thermal actions, etc., that allow for creating sensors, energy converters, and other devices with functional electronics at their base. The nonlinear materials demonstrating hysteresis, such as vanadium dioxide, which has a memory effect, are also a point of attraction for researchers from different disciplines.

Another prospective area for the application of nonlinear materials is microwave electronics. Ferroelectrics and ferromagnetics are widely used in this field. These materials have become a base for elaborating controlled elements and devices with unique characteristics. This Special Issue will be of interest to a wide community across disciplines such as condensed matter and materials science, technology, and devices engineering.

Manuscript Submission Information

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. Molecules is an international peer-reviewed open access semimonthly 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.
