The latest answer given by scientists at the Massachusetts Institute of Technology in the United States is that "magnetic gases" can be created through refrigeration technology. Scientists found that when the temperature drops to 0.00015 degrees Celsius from Absolute zero, the gaseous lithium atoms can show their magnetic properties.

In essence, the laser is to keep the atoms still and reduce the Thermal motion of the atoms, thereby reducing the temperature of the gas. After the initial expansion of lithium gas clouds, they begin to contract. After the laser is turned off, the contraction has the speed of expansion, indicating that the lithium atoms have become magnetic.

From a holistic theoretical perspective, this is very important as it provides us with an easy to understand magnetic property on the smallest possible scale.

This experiment does not imply scientific achievements, but rather theoretical breakthroughs that will have the most practical impact. In the field of data storage, it is particularly evident that many physical laws that computer memory composed of tiny magnetic particles follows are better explained by this discovery.
