Structural and Magnetic Characterization of the Series La1-xSrxFe0.8Cr0.2O3-δ (...
Ramos, T.; Carvalho, M. D.; Ferreira, L. P.; Cruz, M. M.; Godinho, M.A series of perovskite compounds with the general formula La1-xSrxFe0.8Cr0.2O3-δ (x = 0.2, 0.4, 0.6, and 0.8) have been synthesized using a urea/nitrates self-combustion route. Their characterization was performed using room-temperature X-ray diffraction, electrical and magnetization measurements. A structural transition from orthorhombic (x = 0.2) to rhombohedral (x > 0.2) was determined. Among the rhombohedra...
Study of RFe12−xMox (R =Y, Ho) compounds by neutron powder diffraction, ac susc...
Campos, J. Ayres de; Ferreira, L. P.; Cruz, M. M.; Gil, J. M.; Mendes, P. J.; Ferreira, I. C.; Bacmann, M.; Soubeyroux, J.-L.; Fruchart, D.; Godinho, M.Neutron powder diffraction, magnetization and ac susceptibility measurements were performed on compounds of the series RFe12−xMox (R D Y and Ho, x D 1, 2, 3). The influence of the Mo content on both structural and magnetic properties is discussed. Comparison with published data for different Mo concentrations is made. It is found that the effect of Mo substitution for Fe on structural and magnetic properties ca...
A clinical case of chronic thrombotic thrombocytopenic purpura.
Santos, A B; Cruz, M M; Gouveia, JThis is a TTP report of the case of a 29 year old female who entered into apparent complete clinical remission, after EP with fresh frozen plasma and corticotherapy. Unusual large plasma Factor VIII: vWF by two-dimensional Immunoelectrophoresis is the biological change described by Moake and Sufficient in itself to confirm the chronic TTP diagnosis. ; This is a TTP report of the case of a 29 year old female wh...
