Dear Colleagues,

Multiferroic materials, which have two or more ferroic orders, such as ferroelectricity, ferromagnetism, and ferroelasticity, have gained increasing levels of interest in the world of novel multifunctional materials due to the interaction between spin and charge. Because of the highly desired strong coupling between ferroelectricity and ferromagnetism, magnetoelectric materials have received strong research interest. The magnetoelectric (ME) effect is the coupling between polarization (P) and magnetization (M). The influences of the magnetoelectric effect on multiferroics are expected to have a significant impact on the production of advanced electromagnetic devices in the future.

With the development of nanoscience, magnetoelectric materials based on metals, oxides, semiconductors, polymers, and their combinations have attracted more research attention because of their versatility and excellent properties, which can improve their performances in various applications. Developing novel magnetoelectric materials and exploring their applicability has become the focus of a wider range of research fields, including the development of materials, sensors, and actuators, and biomedical applications. Although the research community has made positive progress in these areas, it is still necessary to discuss the main problems that should be solved for practical applications, such as performance improvement, in-depth understanding of the physical and chemical properties of the materials, processability, equipment integration, and reliability. It seems worth noting that open questions, problems, and challenges continue to emerge, providing a source of future research ideas and applications. At present, much work has been devoted to the theoretical and experimental research of magnetoelectric materials and different devices based on them. In terms of the theory and application of the magnetoelectric effect, it is very meaningful to propose a collection of best works.

In this Special Issue, we invite front-line researchers and authors to submit original research and review articles that explore magnetoelectric materials at different length scales. This Special Issue will discuss the main directions of magnetoelectric materials development in order to generalize and provide recommendations for future research focusing on design, synthesis, characterization, theoretical description, recent developments in single-phase and composite form, and their applications in novel device architectures.

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. Crystals 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 2600 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.
