Special Issue Information

Dear Colleagues,

The aim of this Special Issue is to emphasize the relationships between the internal microstructure of modern magnetic materials and their mechanical properties. One obvious example is provided by composite materials comprising at least two different phases, magnetic and non-magnetic (e.g., micro- and nano-sized magnetic particles embedded into a polymer matrix). Different arrangements of embedded particles may lead to different mechanical properties and their dependences on the applied magnetic field. In magnetic alloys, microstructural effects including grain size, precipitation, and structural order parameter may significantly effect magnetic and mechanical properties.

We would be happy to publish experimental and theoretical studies where the abovementioned relations between the internal material structure and the resulting mechanical properties becomes visible. The mechanical properties of interest could be of any kind (elastic modulus, viscoelasticity, hardness, shape memory effect, etc.). Both soft and hard magnetic materials are of interest, which could be in the bulk form, thin films, or coatings. Technological papers where different material microstructures can be realized by ingenious fabrication methods (e.g., additive manufacturing) also fall within the scope of this Special Issue. Finally, we hope to attract papers demonstrating applications which explore the interplay between the internal material structure and mechanical properties in magnetic fields.

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. Materials 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 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.

Magnetoactive elastomers (MAEs) have gained significant attention in recent years due to their wide range of engineering applications. This paper investigates the important interplay between the particle microstructure and the sample shape of MAEs. A simple analytical expression is derived based on geometrical arguments to describe the particle distribution inside MAEs. In particular, smeared microstructures are considered instead of a discrete particle distribution. As a consequence of considering structured particle arrangements, the elastic free energy is anisotropic. It is formulated with the help of the rule of mixtures. We show that the enhancement of elastic moduli arises not only from the induced dipole–dipole interactions in the presence of an external magnetic field but also considerably from the change in the particle microstructure.
