The scientific world has recently made another great and surprising discovery. While it has been observed that the atoms of irregular magnetic materials freeze when cooled, the opposite has been observed for the first time in history. A heated magnetic material was found to freeze.
According to the research published in the journal Nature on July 4, the material in question was an element called ‘neodymium’, which has been described as ‘self-induced spin glass’. These spin glasses are alloys that are formed when iron atoms are randomly dispersed between copper atoms. The north and south magnetic poles of all atoms point in different directions.
Heated element ‘frozen’:
The neodymium element, which is especially used in magnet making, does not act like a magnet on its own. In fact, the discovery that neodymium is a self-induced spin glass took place just two years ago. Scientists working on the element wanted to see how the element reacted to changing temperatures this time.
When the element was heated, a result appeared that did not fit anything natural. Under normal conditions, especially in magnets, heating made the magnetic poles of the atoms irregular, whereas the opposite happened in neodymium. It was observed that neodymium heated from -268 degrees Celsius to -265 degrees Celsius gave the same reaction when other materials were cooled. So the magnetic poles were aligned with each other.
There is no clear explanation for this situation, which is not seen under normal conditions in magnetic materials. But scientists state that they will conduct new studies to illuminate the reason behind this strange behavior.
