application of antiferromagnetic materials


These findings have changed our perception of antiferromagnetic substances from materials lacking practical application to promising candidates for active elements of electronics. Until now, the motion of electron spin in antiferromagnetic materials has not yet been studied well. by Bioengineer. Antiferromagnetic materials. The most obvious application of an AFM material is the phenomenon of exchange bias, already widely used in applications such as spin valves (Park et al., 2011). Quantum materials are worldwide in the focus of research activities within diverse scientific disciplines. In nature, antiferromagnetic order is ubiquitous compared to ferromagnetic order. In materials that exhibit antiferromagnetism, the magnetic moments of atoms or molecules, usually related to the spins of electrons, align in a regular pattern with neighboring spins (on different sublattices) pointing in opposite directions. This material class appears to be increasingly complex and rich in physical phenomena such as magnetism, superconductivity or topology, and is therefore extremely promising for technological advances in the fields of information processing, sensors, computing and many more. Some antiferromagnetic materials have Néel temperatures at, or even several hundred degrees above, room temperature, but usually these temperatures are lower. A group of materials made from the alloys of the rare earth elements are also used as strong and permanent magnets (a popular one is neodymium). 1). Antiferromagnetic Material's Giant Stride Towards Application The "forgotten" world of antiferromagnets (AFM), a class of magnetic materials, offers promise in future electronic device development and complements present-day ferromagnet-based spintronic technologies (Fig. November 12, 2020. Different materials react to the application of magnetic field differently. Antiferromagnetic Material – Antiferromagnetism. Accordingly, only certain materials (such as iron, cobalt, nickel, and gadolinium) exhibit strong magnetic effects. This, however, also requires the presence of a ferromagnet interfaced with the AFM component. 1). The Néel temperature for manganese oxide, for example, is 122 K (−151° C, or −240° F). Antiferromagnetic order occurs commonly among transition metal oxides, such as NiO, and metallic alloys such as FeMn. Antiferromagnetic Material's Giant Stride Towards Application 2020-11-12 The quest for high throughput intelligent computing paradigms - for big data and artificial intelligence - and the ever-increasing volume of digital information has led to an intensified demand for high-speed and low-power consuming next-generation electronic devices. We have shown the various applications and fonctions of magnetic materials in general. Such materials are called ferromagnetic, after the Latin word for iron, ferrum. In an antiferromagnet, unlike a ferromagnet, there is a tendency for the intrinsic magnetic moments of neighboring valence electrons to point in opposite directions. Metals. Abstract. From the theoretical point of view, the newly found phenomena are related to the complicated structure of antiferromagnets compared to their ferromagnetic counterparts. The “forgotten” world of antiferromagnets (AFM), a class of magnetic materials, offers promise in future electronic device development and complements present-day ferromagnet-based spintronic technologies (Fig. In the following, we briefly present materials that are promising for antiferromagnetic spintronics. 2.
