TL;DR: This work reports the first study of isolated nanoscale wires with diameters smaller than 100 nm, for which singledomain states could be expected, and obtained unique insight into the process of magnetization reversal by measuring histograms of the switching field as a function of the orientation of the wires in the applied field, their diameter, and the temperature.

TL;DR: A method to preserve enhanced (“hyperpolarized”) magnetization by conversion into long-lived states (LLS) is designed and it is shown that these enhanced long- lived states can be generated for proton spins, which afford sensitive detection.

TL;DR: In this article, the coercivity of nanocrystalline Fe and Ni produced by inert-gas condensation is investigated and a random-anisotropy model that predicts that the effective anisotropic constant is reduced by averaging over magnetically coupled grains is presented.

TL;DR: In this article, a nonvolatile random access memory (NVRAM) with magnetoresistive memory elements (1) connected by sets of non-intersecting conductor sense lines (3, 4, 5 ) is presented.

TL;DR: The thermogalvanic voltage (TGV) as discussed by the authors measures the ac voltage response to a small temperature oscillation while a dc current is driven through the sample, and it has a magnetic response (MTGV) of 50%, much larger than magnetoresistance (GMR) and the magneto-thermoelectrical power (MTEP).
