Until now, scientists were only aware of the presence of insulators exhibiting one-dimensional magnetism. However, a team of researchers has observed unique one-dimensional magnetism in Ti₄MnBi₂.
“We proved the existence of a new class of quantum materials that are both metallic and one-dimensional magnets, with strong coupling between the magnetic moments and their metallic host,” Meigan Aronson, one of the researchers and a professor at Blusson Quantum Matter Institute (UBC Blusson QMI), said
These findings also provide evidence of a phase space—a concept used in physics to describe all the possible states of a system. It’s like a map where every point represents a unique combination of the system’s variables, such as position and momentum.
Ti₄MnBi₂ is only the second known metallic material with proven one-dimensional magnetism (the other is called Yb₂Pt₂Pb). It’s also the first material where the magnetism is found strongly connected to its metallic nature, making it truly unique.
