Cerium hexaboride challenges physicists to develop new theory

Scientists from MIPT and other research institutes and universities have discovered unusual phenomena occurring in a single cerium hexaboride (CeB6) crystal. By performing an electron spin resonance (ESR) experiment, the researchers confirmed the status of the material, which has been dubbed an “exception to exceptions,” as its behavior defies any explanation in terms of existing models and conventional theories. The research findings were published in Scientific Reports.
