Quantum Oscillations in Flux-Grown with Embedded Aluminum
Abstract
SmB 6 is a candidate topological Kondo insulator that displays surface conduction at low temperatures. In this study, we perform torque magnetization measurements as a means to detect de Haas–van Alphen (dHvA) oscillations in SmB 6 crystals grown by aluminum flux. We find that dHvA oscillations occur in single crystals containing embedded aluminum, originating from the flux used to synthesize SmB 6. Measurements on a sample with multiple, unconnected aluminum inclusions show that aluminum crystallizes in a preferred orientation within the SmB 6 cubic lattice. The presence of aluminum is confirmed through bulk susceptibility measurements, but does not show a signature in transport measurements. Lastly, we discuss the ramifications of our results.
