Magnetic Materials: Synthesis, Structure, Properties, Applications, Modeling and Simulation of Magnetization Processes

Dear Colleagues,

Magnetic materials, which in antiquity attracted the attention of philosophers and scientists due to being considered enlivened stones or carriers of a magical fluid, became the basis for the unprecedented development of humanity following the invention of the electric battery by Volta in 1805. Based on the experimental and theoretical contributions of Faraday, Oersted, and Maxwell in electromagnetism and the propagation of electromagnetic waves, the present and future of our society, based on knowledge, has become foreshadowed in a world that is now what we call the IoT world.

If, in some absurd scenario, magnetic materials had suddenly lost their specific properties, this invitation would never have reached you. However, the design, synthesis, characterization, modeling, and implementation of IoT magnetic materials in a variety of different applications is of great interest and encapsulates the theme of this Special Issue, to which you are invited to contribute with the latest research results of your group.

Magnetic materials are used in the transport and transformation of electricity, communications, information processing, artificial intelligence, environmental protection, and medicine—in short, the sustainable development of our society. The contribution of chemistry, physics, and biology to knowledge of the processes of synthesis and characterization of the properties of various categories of magnetic materials has substantiated, for those interested, the applications that today’s society benefits from. The theoretical explanation of electromagnetic phenomena as well as modeling and simulation of magnetization processes have a complicated but coherent history that began in the early 19^th century and, today, rely on specialized software that scientists, physicists, and engineers can access with a click.

Thousands of research groups from universities, institutes, or research departments around the world are focusing on magnetic materials for various applications. The efficiency of the methods of obtaining reproducible magnetic materials with the desired properties is supported by fundamental research or industrial implementation design. The methods have evolved in recent decades from the classical reaction of metal oxides in solid or liquid phase to high-complexity chemical methods or atomic layer deposition or laser-assisted synthesis, to name but a few. Magnetic materials can be amorphous or crystalline materials, with magnetization domains of nanometric or micrometric dimensions, single-phase or multiphase, high-entropy alloys, or spin glasses. Understanding the origin of magnetism and the electrical and magnetic properties of magnetic materials has evolved extraordinarily in the last century, together with the methods for structural and magnetic characterization. Researchers can use now phenomenological or mathematical models to explain magnetic properties or to simulate the operation of devices that incorporate magnetic materials in simple or highly complex methods.

We believe that there are numerous researchers in the field of magnetism and magnetic materials that are further pushing the limits of knowledge in this field and, moreover, are open to communicating their results in this Special Issue. The scope of this Special Issue within the given theme is broad, and there is no intention to focus on a certain category of methods, materials, models, or magnetization processes.

This Special Issue aims to provide interested readers with the results of state-of-the-art research in the field of magnetism and magnetic materials that push the boundaries of knowledge and report on magnetic materials that are ready to be implemented in medical and industrial applications.

We kindly invite you to submit a manuscript to this Special Issue. Full papers, communications, and reviews are all welcome.
