Local shear waves attenuation measurements by the MR methods

The essential feature of the method is the employment of Elasto-Magnetic Resonance Spectroscopy (EMRS) for precise local measurements of the attenuation of shear elastic waves introduced into a biological sample. Such a measurement can be accomplished by combining the EMRS method with such methods, in which collective dislocations of spins are induced by external physical factors, such as variable electric field, strong magnetic field gradient or longitudinal elastic wave. Theoretical bases of the method presented, related with the external factors, are discussed in the present paper.

Magnetic field profiling for selected-states magnetic-resonance spectroscopy (SSMRS) and Stern-Gerlach spectroscopy (MGRS) in condensed matter

A method was presented of profiling the magnetic field, with a zero vector of magnetic flux density $B_{r}$ and strong gradient G, enabling conditions for the Stern-Gerlach spectroscopy to be accomplished in condensed matter (the method has been called magnetic field gradient spectroscopy - MGRS), as well the previously proposed magnetic resonance spectroscopy for selected energy states (SSMRS). Magnetic field distribution in a model electromagnet were shown when condition $B_{r}= 0$ for resultant magnetic field was satisfied within the sample
