Abstract:
Results of an ultrasonic investigation of EuB6 at low temperatures are reported. Both longitudinal and transverse acoustic modes exhibit anomalies in the vicinity of the low-temperature phase transitions of EuB6. The ultrasound data serve to establish part of the B-T phase diagram of EuB6. At magnetic fields exceeding 3 T, magneto-acoustic quantum oscillations (MAQO) are observed. The nature of the acoustic anomalies and possible phases in external magnetic fields are discussed. Also a comparison with the elastic properties of other rare-earth (RE) hexaboride compounds is made.
