The De Haas–van Alphen effect is a quantum mechanical phenomenon occurring in materials exposed to strong magnetic fields at very low temperatures. It reveals insights into the electronic structure of metals and semimetals. Under these conditions, the material’s magnetic susceptibility oscillates periodically with changes in magnetic field strength. These oscillations are tied to the quantized electron orbits in the material’s Fermi surface, School Management System representing the boundary of electron energy levels in momentum space. This effect aids in understanding electron behavior in materials, offering crucial information for comprehending electronic properties and potential applications in fields like superconductivity and electronic devices.
