Short-range effects and magnetization reversal in CoFe thin films: a MOKE magnetometry/domain imaging and AMR study
J. M. Teixeira, R. F. A. Silva, J. Ventura +8
A MOKE magnetometry unit simultaneously sensitive to both in-plane magnetization components, based on an intensity differential detection method, allows us to observe the uniaxial…

Magnetic tuning of tunnel conductivity
Yu. G. Pogorelov, J. B. Sousa, J. -P. Araujo
Using the simplest two-subband Stoner model, it is shown that the variation of the Fermi energy under applied magnetic field is inverse proportional to the spontaneous magnetizatio…

Influence of charge ordering on the magnetocaloric effect of (Pr,Ca)MnO manganites
M. S. Reis, V. S. Amaral, J. P. Araujo +3
In the present work we analyze the influence of the charge-ordering on the magnetocaloric effect of PrCaMnO manganites. The results for the samples with 0.30 pr…
