A new method for polarizing nuclei, applicable only to metals, is proposed. It is shown that if the electron spin resonance of the conduction electrons is saturated, the nuclei will be polarized to the same degree they would be if their gyromagnetic ratio were that of the electron spin. This action results from the paramagnetic relaxation processes that occur by means of the hyperfine structure interaction between electron and nuclear spins. A shift of the electron spin resonance due to the same interaction will occur for large amounts of polarization and should provide a direct indication of the degree of polarization.read more

Magnetic sensors and their applications
J. Lenz,S. Edelstein +1 more
TL;DR: Magnetic sensors can be classified according to whether they measure the total magnetic field or the vector components of the magnetic field as discussed by the authors, and the techniques used to produce both types of magnetic sensors encompass many aspects of physics and electronics.

Nonlocal magnetization dynamics in ferromagnetic heterostructures
TL;DR: In this article, the role of spin pumping in layered structures is discussed and the main body of the theory is semiclassical and based on a mean-field Stoner or spin-density functional picture, but quantum-size effects and electron-electron correlations are also discussed.
