Domain State Occurring in the de Haas–van Alphen Effect in Silver

Hysteresis has been observed in de Haas–van Alphen measurements of the Condon domains in silver, and it shows the first-order nature of the transition to the domain state. The hysteresis, and thus the first-order nature, is manifested in a nonlinear effect where a double-valued response of the amplitude with the applied external field is observed.
