"... Gravitomagnetism is a phenomenon predicted by Einstein’s theory of General Relativity, it consists in the interaction generated by a mass current in a way formally similar to magnetism generated by an electric current. A number of experiments have been proposed and carried out to accurately measure ..."

"... The quadratic form of the Dirac equation in a Riemann spacetime yields a gravitational gyromagnetic ratio κS = 2 for the interaction of a Dirac spinor with curvature. A gravitational gyromagnetic ratio κS = 1 is also found for the interaction of a vector field with curvature. It is shown that the Di ..."

On Some Gravitomagnetic SpinSpin Effects for Astronomical Bodies, in press, Int
 J. of Mod. Phys. D
"... In this paper we look at the gravitational spin–spin interaction between macroscopic astronomical bodies. In particular, we calculate their post–Newtonian orbital effects of order O(c −2) on the trajectory of a spinning particle with proper angular momentum s moving in the external gravitomagnetic f ..."

GravitoMagnetism in onebody and twobody systems: Theory and Experiments
 Proc. Int. School Phys. “Enrico Fermi" Course CLXVIII, Varenna, Italy, 2007, in press, [arXiv:0804.3806
"... Summary. — We survey theoretical and experimental/observational results on generalrelativistic spin (rotation) effects in binary systems. A detailed discussion is given of the twobody Kepler problem and its first postNewtonian generalization, including spin effects. Spin effects result from gravi ..."

, 2008
"... We consider two types of mechanical coupling between the crust and the core of a precessing neutron star. First, we find that a hydromagnetic (MHD) coupling between the crust and the core strongly modifies the star’s precessional modes when ta ≤ ∼ (Ts × Tp) 1/2; here ta is the Alfven crossing timesc ..."

Second, we consider the effect of gravitomagnetic coupling between the neutron superfluid in the core and the rest of the star and show that this coupling changes the rate
