Magnets Turned out to Behave Like Liquid Under Laser

Ezio Iacocca and Mark Hoefer of the University of Colorado Boulder, published this week in Nature Communications, investigated the effects of laser on the characteristics of magnets. The research revealed the kind of results that will change the perspective on magnets.

Stating that magnets have a highly organized particle structure by nature, Ezio Iacocca drew attention to the upward and downward movements of atomic building blocks. Stating that these rotation movements are similar to the fact that the Earth’s magnetic field always points to the north, Iacocca stated that if these rotations can be controlled, very fast magnetism-based data storage devices can be produced.


In the study, in which it was stated that decay occurs in the magnet with a very short-term laser pulse, it was stated that the up and down movement of the particles with the laser effect dispersed in all directions and the magnetic properties disappeared because of this.

The team designed an experiment to investigate the unknowns that emerged during the experiments; blasted the alloy of gadolinium, iron, and cobalt with a laser and reached the most intriguing result of the research. The researchers, who determined that the magnets show rotational movements as in liquid substances, although they do not actually liquefy, aim to use the results they obtained in developing new technologies.
