IBM creates World’s Smallest Magnet to store single bit data

Yes you read it correct.

A research team at IBM has created the world’s smallest magnet using a single atom which can store one bit of the data on it.

Currently the hard disk drives use about 100,000 atoms to store a single bit. This discovery was published in the journal Nature on 8th March, 2017.

The ability to read and write one bit on one atom may lead to developing significantly smaller and denser storage devices in future that can store the entire iTunes library of 35 million songs on a device.

The IBM scientists used a Scanning Tunneling Microscope (STM) to build and measure isolated single-atom bits using the Holmium Atoms.

They used an electrical current to write and read binary data (1s and 0s) on the atom. The invention can allow people and businesses to store 1,000 times more information in the same space and one day make data centers, computers and personal devices radically smaller and more powerful.

What is an IBM?

IBM is known as International Business Machines Corporation founded by Charles Ranlett Flint on 16th June, 1911, which is headquartered in New York, United States. IBM is an American multinational technology company with operations in over 170 countries.

The company originated in 1911 as the Computing-Tabulating-Recording Company (CTR) and was renamed “International Business Machines” in 1924. In 1986, IBM Research won the Nobel Prize for inventing the Scanning Tunneling Microscope used to view and move singe atoms.

Today they use the microscope to deliver an electric current that turns the magnetic direction in a single atom up or down and freezes it in place and representing the read-write properties of today’s hard drive.

IBM manufactures and markets computer hardware, middleware software and offers hosting and consulting services in areas ranging from mainframe computers to Nanotechnology
