“Ferromagnetic (FM) material dependence of the uncompensated (UC) antiferromagnetic (AF) moments in AF/FM exchange biased bilayers has been studied using the x-ray magnetic circular dichroism technique in the AF/FM
(AF = gamma-Mn-Ir, FM = Ni-Co, Co-Fe, Fe-Ni) bilayers. The direction and magnitude of the UC-Mn moment change significantly when the composition of the FM layer changes. The crystal structure of the FM layer affects
the magnitude of the UC-Mn moments. The UC-Mn moments and the FM moments of Fe-rich alloys prefer the anti-parallel alignment. Conversely, the UC-Mn moments align parallel to the FM moments in Co-rich or Ni-rich regions. A first-principles calculation pertaining to the L1(2)-Mn(3)Ir/FM (FM = Ni(4-n)Co(n), Co(4-n)Fe(n), Fe(4-n)Ni(n); n = 0, 1, 2, 3) bilayer system was carried out to characterize the UC-Mn moments near the interface. It was found that the UC-Mn moments originate from the reorientation of the magnetic moments of Mn and other ferromagnetic atoms near the AF/FM interface. The see more calculated result for the compositional dependence of the UC-Mn moment is in good agreement with the obtained experimental data. As a result, the dependence of the UC-Mn moment on the composition of HKI-272 inhibitor the FM layer can be explained qualitatively based on the model that the band filling fraction modifies the direction and the magnitude of exchange coupling between AF and FM atoms, depending on the crystal structure and the composition of the FM layer.

“Purpose. This study evaluated F-18-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) findings in patients with Kikuchi disease (KD), or histiocytic necrotizing lymphadenitis.\n\nMaterials and methods. We evaluated the F-18-FDG PET/CT findings of seven patients (one man, six women) with KD, ranging in age from 23 to 66 years (mean 36 years). All the patients had been diagnosed based on the pathological findings of a biopsy and clinical course.\n\nResults. The maximum standard uptake values (SUVmax) of FDG uptake in affected lymph nodes were 2.05-13.94 (mean +/- SD, 6.25 +/- 3.32). In all the patients but two, the lymph nodes with the SUVmax were located in the neck. All the lymph nodes had a diameter of <30 mm. In nonneck regions, the SUVs of the swollen lymph nodes tended to indicate lower uptake.\n\nConclusion. FDG-PET/CT was capable of visualizing general regions containing lymph nodes and was useful for making clinical decisions as to biopsy sites.
