Electron magnetic resonance: The modified Bloch equation

Bilha Segev, Y. B. Band

Research output: Contribution to journalArticlepeer-review


We find a modified Bloch equation for the electronic magnetic moment when the magnetic moment explicitly contains a diamagnetic contribution (a magneticfield-induced magnetic moment arising from the electronic orbital angular momentum) in addition to the intrinsic magnetic moment of the electron. The modified Bloch equation is coupled to equations of motion for the position and momentum operators. In the presence of static and time varying magnetic field components, the magnetic moment oscillates out of phase with the magnetic field and power is absorbed by virtue of the magnetic-field-induced magnetic moment, even in the absence of coupling to the environment. We explicitly work out the spectrum and absorption for the case of a p state electron.
