英文摘要
We have developed high magnetic field multi-frequency electron spin resonance (ESR) apparatuses that can measure down to 0.1K in a static magnetic field and down to 0.6K in a pulsed magnetic field to study two kinds of magnets with remarkable quantum effects and competing exchange interactions. We have found novel ESR signals above a critical field where the energy gap vanishes which were not observed at the temperatures down to 1.3K for the former, and the shift of an ESR resonance field for the latter.
