摘要

The electronic structures of organic conductors are highly anisotropic and sensitive to applied pressures, since they are composed of molecules. As a result, various electronic phases such as those that are antiferromagnetic, spin-singlet, spin-density-wave, and superconducting are stable within a narrow pressure range. Competition between these electronic phases in organic conductors has attracted a great deal of attention. Magnetic resonance measurements are advantageous for studying fundamental electronic properties and for understanding the detailed electronic structures of organic conductors. Investigations into such electronic phases using magnetic resonance measurements are important to understanding unsolved fundamental problems in the field of solid state physics, and to explore novel functionalities in the field of material science. This paper introduces broad-line NMR and ESR investigations into molecular-based conductors to enable better understanding of electron spin dynamics and functionality in low-temperature electronic phases.
