Summary:

Quantum materials, defined by their photon-like electrons, are opening new frontiers in material science. Researchers have synthesized organic compounds that display a universal magnetic behavior tied to a distinctive feature in their band structures called linear band dispersion. This discovery not only deepens the theoretical understanding of quantum systems but also points toward revolutionary applications in next-generation information and communication technologies that conventional materials cannot achieve.

Unique physical properties of materials have been the center of interest in material science community. Among them, quantum materials have recently garnered growing attention, because of their unprecedented physical properties governed by photon-like electrons. We have synthesized a series of organic compounds of as a new member of quantum materials.

After theoretical and experimental examination, we have discovered universal features of magnetic behavior shared by them. Based on our original theoretical model, the behavior is directly related to a characteristic feature of their band structures called linear band dispersion (LBD). Accordingly, such magnetic behavior is intrinsic and universal to quantum materials with LBD.

The findings here will accelerate the understanding and application of quantum materials, which will enable advanced information and communication technology that other materials cannot achieve.
