Revolution in magnetism: Mit-researchers discover P wave magnetism!

A groundbreaking discovery in the field of physics could have far -reaching effects on technology. Researchers at the Massachusetts Institute of Technology (with) have identified a new type of magnetism, known as a P-wave magnetism, which combines both the properties of ferromagnetism and anti-ferromagnetism in a unique combinatorial approach. This discovery was presented in a current publication in the journal Nature on May 28th.

magnetism is a fundamental physical force that plays a key role in our everyday life, from refrigerators to electric motors. The basics of magnetism are based on the alignment of atoms and electrons in a magnetic field. Ferromagnetic materials, such as iron, nickel and cobalt, show a parallel alignment of their atomic pins, making them create strong magnetic fields. In contrast, antiferromagnetic materials cause neighboring atoms to align, which means that their magnetic properties are canceled.

Discovery of the P-wave magnetism

The new magnetic phase was discovered in nickeliodide (NII₂), a two -dimensional crystalline material. In this material, the electrons show a preferred spin orientation that is reflected in spiral configurations. Researchers found that the spins of the electrons can be switched to the spin spiral by creating an electrical field. This opens up the possibility of dynamic control of the magnetic properties of the material, which can be influenced by external electrical tensions.

The experiments that led to discovery were carried out under controlled conditions. The researchers synthesized nickeliodide by separating elements on a crystalline substrate and their subsequent heating. The analyzed data show that the spins of the electrons correlate with the handfulness of the polarized light used. With ultra-kalten temperatures of around 60 Kelvin, P wave magnetism was observed, which opens up the possibility of finding materials with these properties at room temperature in the future.

potential in technology

The discovery of P-wave magnetism has the potential to produce significant changes in technology, especially in the area of ​​spinronics. This technology aims to use electron spin instead of electrical loads for data storage. The advantages are promising: a higher memory density, faster processing speeds and lower energy consumption could follow. There are also possible uses in sensors and the automotive industry.

The research work on the MIC is in line with a larger field for manipulation of electron pins. Similar efforts are made at other international institutions, such as the Johannes Gutenberg University Mainz. While the P-wave magnetism is a promising discovery, the next challenge remains to identify materials that have these special properties even at higher temperatures.

Progress in research on magnetic phase transitions and their applications is not only important for the basic science. Such transitions are crucial for understanding how materials change their magnetic conditions, which can have a direct impact on innovative technologies in data storage and material development. The possibility of influencing magnetism through temperature changes or pressure transmissions is also of great interest and could open up new ways in physics and beyond.
