Spin-spin relaxation
WebAug 5, 2024 · Spin-phonon coupling is the main driver of spin relaxation and decoherence in solid-state semiconductors at finite temperature. Controlling this interaction is a central … In physics, the spin–spin relaxation is the mechanism by which Mxy, the transverse component of the magnetization vector, exponentially decays towards its equilibrium value in nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). It is characterized by the spin–spin relaxation time, known as T2, … See more When excited nuclear spins—i.e., those lying partially in the transverse plane—interact with each other by sampling local magnetic field inhomogeneities on the micro- and nanoscales, their … See more A spin echo experiment can be used to reverse time-invariant dephasing phenomena such as millimeter-scale magnetic … See more • Relaxation (NMR) • Spin–lattice relaxation • Spin echo See more

WebWhat are spin-spin interactions? In the previous Q&A we showed how molecular motion of two dipoles could create locally fluctuating magnetic fields resulting in T1 and/or T2 relaxation. A somewhat different way to look at the dipole-dipole interaction with a quantum mechanical bent involving energy levels is presented below. WebApr 2, 2024 · Relaxation is the process in which spins release the energy received from a radiofrequency pulse. MRI signal is influenced, among other factors, by different types of relaxation: T1 relaxation (spin-lattice or longitudinal relaxation) T2 relaxation (spin-spin or transverse relaxation) T2* relaxation (reflecting both T2 relaxation and magnetic ...
