A team of physicists at New York University has discovered a new kind of magnet that could improve data storage technology in computers.

The magnets are called "singlet-based magnet" and differ from the traditional type of magnet in its small components, which form a strong magnetic field, the university statement said.

The new type also has the ability to switch between magnetic and non-magnetic conditions quickly and smoothly with various speeds in the devices, a feature that can support the technology of data storage in computers well, in addition to the advantage of energy saving during the transition between magnetic cases.

Perhaps these features are what made scientists optimistic about this type of magnetism, which they considered a promising model to enhance the performance of data storage technologies.

He said d. Andrew Ray, assistant professor who led the research team in the university statement, "We have been able to discover this new magnet in a compound of uranium and antimony known as USB2, it contains fields that come out of its field and end in the same area, leading to an unstable power, but more flexible than Traditional counterparts ".

Commenting on the properties and features of the new magnet and the record of the uranium compound and antimony, Ahmed El-Gendy, Assistant Professor, Department of Physics and Director of the Laboratory of Magnets of Nanomaterials and Biomaterials at the University of Texas in Palasso, United States of the island Net "advantage of the research team that he succeeded in preparing this type of vehicles to give magnetic properties at a temperature of minus 70 degrees Celsius, which is the strongest competition for previous attempts For such compounds which gave magnetic properties at minus 170 degrees Celsius. "

"However, they still can not compete with materials that give high magnetic properties at room temperature, so the use of these magnets will cost a lot for their need for liquid nitrogen to show the properties of these materials. In addition, uranium is a rare and expensive material Price, and this will not match the needs of global markets in the components of cheap and high-efficiency to produce computers with high storage capacity.

The discovery of the new magnet comes after a series of research published by the New York University team at the British journal Nature Communications on the use of magnetism and magnetism to improve computer data storage technologies.

The latest research was a paper published on 7 February with the participation of scientists from some American research centers, which resulted in scientists being able to discover this new magnet. The research focused on studying the magnetic temperature on the electronic composition of the uranium and antimony compound (USb2).

In this regard, says Dr. "These types of magnets may have a great ability to change their magnetic properties in a very short time, but it is difficult to apply in normal circumstances because they need to be isolated from the air while maintaining the temperature at minus 70 degrees Celsius, and these conditions get expensive Making them expensive when they are presented to international markets.
