“…The remaining width relative to unpinned Py may be related to the variable oxidation states of the surface species, which can allow additional relaxation mechanisms, especially since Fe is present. 5 Note that the presence of even a thin native oxide on Py adds a significant width. ͑Our earlier work 1 showed that thin Cu or Ni surface layers on Fe polycrystalline films reduced the linewidths to the lowest values reported for metal films, 15 Oe., implicating the role of iron oxides in this line broadening.͒…”

Ferromagnetic resonance (FMR) experiments have been conducted near 9.5 GHz on permalloy (Py) thin films which are components of spin valves and related structures. These so-called giant magnetoresistance structures often use antiferromagnetic NiO to achieve pinning of one magnetic layer. Magnetic anisotropies acting on these pinned layers were deduced by observing their resonances for fields perpendicular to and in the sample plane. We used data taken from 4 to 600 K to identify potential mechanisms of pinning, anisotropy, and linewidth. The anisotropic exchange pinning and an isotropic downward FMR shift vanish at a blocking temperature well below the bulk Neél temperature of NiO. The strong temperature dependencies of the isotropic shift and linewidth may reflect the presence of different spin pinning subsystems and the different time scales of the FMR and low frequency or static measurements.

“…A key flavour component in light-activated milk is methional resulting from the breakdown of the amino acid methionine in the presence of riboflavin (63), but the potato odour of methional may be replaced by the cabbage, burnt-feather odour of methanethiol, dimethyl disulphide and dimethyl sulphide. Free radicals derived from methionine, methional and cysteine combine to form the 3 sulphur compounds:…”

“…Metallic magnetic thin films grown by physical vapor deposition or sputtering can have excellent magnetic softness with low FMR linewidth when their thickness is less than the skin depth ␦ s = ͱ 2 / , where is the resistivity, is the angular frequency, and is the permeability of the magnetic films. [9][10][11][12][13] These metallic magnetic films show great potential for low-cost integrated tunable microwave devices with low FMR linewidth, low processing temperature, high saturation magnetization, 9,11-13 and much higher achievable s , up to 1600 ppm for Terfenol-D 14 and 400 ppm for FeGa ͑Gal-fenol͒ single crystals. 15,16 However, metallic magnetic films bearing all of these properties are not readily available.…”
