(a) AC is injected into an STMD under magnetic field () applied at , and the free-layer magnetization precesses around its equilibrium; (b) a typical - spectrum can be decomposed into a Lorentz peak and an anti-Lorentz curve; (c) frequency bandwidth is defined as frequency gap of at = −10 mT and −60 mT.
