Boron diffusion in magnetic tunnel junctions with MgO (001) barriers and CoFeB electrodes
TL;DR: In this paper, the diffusion of Boron out of CoFeB layers in model systems with thick coFeB and MgO layers grown by radiofrequency sputtering or electron-beam evaporation is probed after annealing by x-ray photoemission spectroscopy (XPS) and electron energy loss spectroscopic analysis.
Nanoscale dissipation and magnetoresistive 1 / f noise in spin valves
TL;DR: In this article, spatial correlations of 1/$f$ noise in yoke-shaped, giant magnetoresistance spin valve sensors are reported, and an upper bound of 135 nm, corresponding to a magnetic volume of 10${}^{5}$ nm/$}^{3}$, is determined for the lateral size of the magnetic fluctuators responsible for the magnetoresistive 1/$ f$ noise.
Magnetoresistance of chromium dioxide powder compacts
TL;DR: In this article, the half-metallic ferromagnetic powders of the halfmetallic granular metal are dielectric granular metals and the negative magnetoresistance is due to tunneling between contiguous magnetagnetic particles along a critical path with a spin-dependent Coulomb gap.
Influence of a magnetic field on the electrochemical rest potential
TL;DR: In this paper, the influence of an external magnetic field on the rest potential of ferromagnetic and non-ferromagnetic electrodes is studied, and an anodic shift is observed when the cathodic corrosion current is mass-transport limited.

TL;DR: The most abundant element in the Earth's crust is iron as discussed by the authors, which accounts for 92% of the atoms in the crust, and the most common metal classes are aluminum and silicon.
