Eli Zeldov IssueVolume: 2024-01-05 Abstract: Quantum oscillations originating from the quantization of electron cyclotron orbits provide sensitive diagnostics of electron bands and interactions. We report on nanoscale imaging of the thermodynamic magnetization oscillations caused by the de Haasvan Alphen effect in moir graphene. Scanning by means of superconducting quantum interference device (SQUID)on-tip in Bernal bilayer graphene crystal axis-aligned to hexagonal boron nitride reveals large magnetization oscillations with amplitudes reaching 500 Bohr magneton per electron in weak magnetic fields。
