Scientists Discover First High-Temperature Single-Molecule Magnet

Even though the idea of giving a magnetic character to a molecule sounds far-fetched, advancements in science somehow always manages to convert such simple and yet complicated idea into a reality. In a recent advancement, a group of scientists have designed a high-temperature single-molecule magnet (SMM) that can retain magnetic information for over a relatively longer period of time, and that too with a blocking temperature of above 77 K, which is the boiling point of liquid nitrogen, that is both cheap and readily available. Previously, it was only possible to synthesize SMMs with blocking temperatures reachable by cooling with expensive and scarce liquid helium which always hindered the Practical applications of SMM’S. But with this development, one can “write” information into molecules leading SMMs, to have various potential applications, such as high-density digital storage media, that can be used as parts of microprocessors in quantum computers. This development can massively increase the storage capacity of hard disks without increasing their physical size.
