Special Issue Information
Dear Colleagues,
For environmental concerns, it is highly desirable to replace gas-based cooling systems with magnetic cooling. Magnetic cooling systems have significant advantages such as small volume, chemical stability, low cost, non-toxicity, not causing sound pollution, and a high density of heat-transfer material—a solid body compared to steam or gas density.
The basis of magnetic cooling is the magnetocaloric effect. It was first observed on a piece of iron by German scientist Emil Warburg in 1881, refers to the change in temperature of a magnetic material as a result of applying a magnetic field.
This physical fact is directly related to the entropy of the material. Namely, when a sufficiently strong magnetic field is applied to a magnetic material that is thermally insulated from its surroundings, the magnetic moments of the material are oriented in the direction of the magnetic field, and this causes the system to form a more ordered magnetic structure. This reduces the entropy of the system. As a result, it raises the system temperature by a few Kelvin to restore the decreased entropy balance. Therefore, the material absorbs heat and cools its surroundings, which forms the basis of magnetic cooling technology.
In recent years, both the production of devices and the production of suitable materials for magnetic cooling systems have been studied more intensively. We invite original contributions and review articles focusing on magnetic entropy, magnetocaloric materials and magnetic cooling systems.

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. 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 2200 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.
