Magnetic Properties and Applications

This issue collects a few articles on “Magnetism and Applications of Magnetic Wires” presented at the 7th International Workshop on Magnetic Wires (IWMW 2015) held in Ordizia (Gipuzkoa, Basque country, Spain) on July 2–3, 2015. As regarding the topic of the Workshop and consequently of this topical section in physica status solidi (a) it is worth mentioning that along few decades soft magnetic wires are considered as one of the most promising magnetic materials for industrial applications in various industrial sectors such as magnetic sensors, microelectronics, security, smart composites etc. 1-6. The main reasons for this continuous interest are related to the possibility of obtaining magnetic wires either with extremely soft magnetic properties or exhibiting so-called magnetic bistability, i.e. perfectly rectangular hysteresis loop 3-7. Moreover magnetically soft wires and microwires can also exhibit giant magnetoimpedance effect (GMI) that usually is related to high circumferential magnetic permeability of magnetic wires 3-8. Usually high magnetic permeability and GMI effect can be observed in magnetic wires with vanishing magnetostriction coefficient 3-9. Moreover, the amorphous character of magnetic wires prepared using rapidly quenching technique allows achievement of even better magnetic softness. Different families of amorphous wires and microwires have been available for more than three decades. During this time, the unique properties of these materials have led to many applications, especially in the field of sensors and electronic devices. Recognizing the importance of these materials for science and technology, six international workshops were organized over the past years, namely: London, UK (1990), Albuquerque, NM, USA (1994), Nagoya, Japan (1999), San Sebastian, Spain (2001), Zumaia, Spain (2008), and Bodrum, Turkey (2010). This proceedings section contains scientific papers presented during last 7-th International Workshop on Magnetic Wires (IWMW) held in Ordizia, 2015. The organization of this meeting is based on the continuing interest of many research and technological groups in the different families of magnetic wires. Along these years the dimensionality has been evolved from almost bulk (120 μm thick wires) through micrometric (10–20 μm thick micro-wires) till nanometric wires, presented in the last three meetings. The 7th IWMW was focused on recent advances in physical effects and related applications, such as magnetization process of thin wires, giant magnetoimpedance effect in thin wires and applications, high frequency properties and metamaterials. In addition to the aforementioned “classical” topics, the recent advances in new materials and applications have been presented in the session “Novel magnetic wires with functional properties”. Finally, it must be mentioned that 23 oral (plenary, invited and oral) and 19 poster presentations, given by participants coming from 15 different countries have been presented. Total number of participants was 49. After rigorous review process, 9 papers have been accepted for publication in the proceedings section of this issue of physica status solidi (a). Therefore, we hope that this topical section will provide real opportunity for researchers, who are involved in this field of magnetism to share new ideas and concepts in this research field and favoring discussions about the future basis and perspectives on the potential technological applications for different industrial sectors. We hope that this issue will bring interesting information to the readers and will be useful for people involved in this subject of scientific research. We would like to express our gratitude to the high level of the invited speakers and to the authors who have contributed to these proceedings. It is worth mentioning that magnetic wires is also an important topic of research in the Basque Country University (UPV/EHU) and particularly in San Sebastián, where this kind of research is carried out by the Magnetic Group of the UPV/EHU. That is why we were encouraged by the International Advisory committee to organize this workshop near to San Sebastián. We acknowledge our Sponsors and Institutions for the economical and moral support. The Workshop was supported by the Vice-Rectorate for Research of the UPV/EHU, by the Research Department of the Basque Government and by the Ordizia municipality. Ordizia is a small village located on the distance of about 40 km from San Sebastian. The IWMW 2015 workshop was organized mostly by the members of the Magnetic Group of the UPV/EHU. We would like to acknowledge the active participation of all members of our Magnetic Group (especially of that participating in the local organizing committee, the conference committee members and the secretariat).
