Uncertainty estimates for magnetic relaxation times and magnetic relaxation parameters

Relaxation times Mapping Using Magnetic Resonance Imaging

Magnetic Resonance Imaging (MRI) techniques have been used to determine the spin-lattice, T1, and the spin-spin, T2, relaxation times in three phantoms with compositions simulating the T1 and T2 values of human tissues. Some methods of analysis were used in order to obtain the relaxation time maps. It has been shown that reliable results can be also obtained by using approximating methods of in...

Relaxation Times in Magnetic Nanoparticles System and Memory Effects

Some memory effects in nanoparticle systems, similar to those seen in spin glass systems, may have important device applications, by tuning the interaction and the particle size. Recently, this subject provoked a special interest in nano-sciences. In this work we present a study, by simulation of the mode in which the behavior of a magnetic nanoparticle system is influenced by the superposition...

Nuclear Magnetic Relaxation

Proton Magnetic Relaxation in Gases

Measurements of the longitudinal nuclear spin relaxation time, Ti, in molecular gases are analogous to non-resonant absorption measurements; Ti is determined primarily by that part of the spin-lattice interaction which couples free molecular states of the same energy. The contribution to Ti of matrix elements of the spin-lattice interaction between rotational states of different energy is quenc...
