The De Haas–Van Alphen effect, often abbreviated to DHVA, is a quantum mechanical effect in which the magnetic susceptibility of a pure metal crystal oscillates as the intensity of the magnetic field B is increased. It can be used to determine the Fermi surface of a material.
The De Haas–Van Alphen effect, commonly known as DHVA, describes a quantum mechanical phenomenon where the magnetic susceptibility of a pure metal crystal changes in response to varying magnetic field strength (B). This effect is useful for determining the Fermi surface of a material.
