Realizing Room-Temperature 2D Magnetic Semiconductors nanomaterials materials semiconductor NatureComms
By Hussain AhmedSep 8 2022Reviewed by Megan Craig, M.Sc. Magnetization in ultrathin nanocrystals offers new avenues for research into novel physics and the development of next-generation flexible electronics. However, very few studies exist on developing a 2D magnetic semiconductor with Curie temperatures greater than ambient temperature.
Such materials pave the way for new possibilities, such as electromagnetic sensing and data storage. 2D ferromagnetic materials must have inherent magnetic states that are robust at or above ambient temperature for the creation of practical semiconductor systems. Magnetic sensors composed of iron oxides and multilayer chromium tellurides are indications of current advancement in this sector.
However, the antiferromagnetic structure with almost zero magnetism value, despite being greater than ambient temperature, severely restricts their practical applications. Highlights of the Current Study In this work, the researchers demonstrate that van der Waals linking may be used to create high-performance cobalt ferrite nanosheets as fine as a single unit cell for use in a novel 2D magnetic semiconductor.
Vibrating sample magnetometry , magneto-optical Kerr effect , and magnetic force microscopy were used to illustrate the hard magnetic activity and in situ magnetic region development in cobalt ferrite nanosheets. This presentation of inherent room-temperature magnetic properties in ultrathin ferrite nanosheets opens the door for developing novel quantum phenomena and device configurations. Also, it provides a new impetus to pursuing other magnetic crystallites that are missing from existing 2D materials.
