Listening for Quantum Oscillations in the Kondo Insulator YbB12
Ultrasonic measurements reveal magnetic quantum oscillations only after YbB12 transitions into a metallic state Magnetic quantum oscillations have been unexpectedly observed in insulators, where freely moving charge carriers are not expected to exist. A joint study by researchers from Tokyo University of Science, The University of Tokyo, and Kobe University investigated this puzzling behavior […]
