Data is best stored on hard disks. It is easier to access when data stored in a hard disk. Of course, they can also be stored online. While there is nothing wrong with storing data online, you would have to rely on the internet to access your files.
With a hard disk, there’s no need to rely on the internet to access your files. Since it’s very convenient to use, a hard disk with huge data storage capacity is always in demand. The thing is, a hard disk with huge data capacity might not be portable. If it’s not portable, then it won’t be that convenient to take everywhere.
Ideally, the size of a hard disk should remain small as its data storage capacity increases. At the moment, that kind of hard disk is a myth. Hopefully, tomorrow, it becomes a reality. Here’s a look at tomorrow’s hard disk.
A recent breakthrough discovery of the world’s first high-temperature single-molecule magnet (SMM) opens doors to future exciting developments in massive storage capacity increase in hard disks without increasing their physical size.
Before the publication of the study Magnetic Hysteresis up to 80 Kelvin in a Dysprosium Metallocene Single-Molecule Magnet led by Professor of Chemistry Richard Layfield at the University of Sussex in England, it was only possible to synthesize single-molecule magnets with blocking temperatures that were reached by cooling with considerable expensive and scarce liquid helium.
The team at the University of Sussex in collaboration with Sun-Yat Sen University in China and the University of Jyväskylä in Finland, reported a new single-molecule magnet (SMM) which is a type of material that retains magnetic information up to a characteristic blocking temperature.
The characteristics of the SMMs are paving way to a very tiny device that could store huge data.
SMMs are molecules with the characteristic of remembering the direction of a magnetic field that has been applied to them over relatively long periods of time once the magnetic field is switched off. This makes possible to write information into molecules.
“Our new result is a milestone that overcomes a major obstacle to developing new molecular information storage materials and we are excited about the prospects for advancing the field even further,” said Professor Layfield.
The fact that digital data was stored in the magnetic field of a single atom is a very significant step in revolutionizing the hard disk.
Single-molecule magnets have the potential for important applications such as high-density digital storage media as well as parts of microprocessors in quantum computers.
This magnetic breakthrough is something to look forward to since we’re always looking for ways and means to store huge data in just one place.
The single-molecule magnet that is set to play such an important role in the future of quantum computing was the result of the co-ordinated effort of three universities.
The synthetic work and characterization of the prepared compounds was carried out by Professor Layfield’s research group while magnetic measurements were performed at Sun Yat-sen University under the leadership of Professor Ming-Liang Tong. Postdoctoral researcher Akseli Mansikkamäki carried out theoretical calculations and analyses at the Department of Chemistry of the University of Jyväskylä.
