Crespo del Arco, Patricia ; Hernando Grande, Antonio ; Yavari, R ; Drbohlav, O. ; Garcia Escorial, A. ; Barandiaran, J. M. ; Orue, I. | American Physical Society | 1993-09-01A ferromagnetic and supersaturated fcc Fe_51Cu_49 solid solution has been obtained by mechanical alloying. After subsequent thermal treatments the fcc phase undergoes a spinodal decomposition which finally, at 780 K, yields a mixture of fcc and [...]texto impreso
Hernando Grande, Antonio ; Crespo del Arco, Patricia ; Escorial Garcia, A. ; Barandiaran, J. M. | American Physical Society | 1993-05-31In conclusion we have proven that the fact that both fcc FeCu and bcc Fe magnetization agree at 300 K is simply an accident and our data at low temperature show clearly that the Fe contribution after precipitation from the metastable phase has a[...]texto impreso
Hernando Grande, Antonio ; Crespo del Arco, Patricia ; Castaño, F. J. ; Arcas, J. ; Multigner, M. ; Barandiaran, J. M. ; Fernández Barquín, L. | American Physical Society | 2000-01-01We report the existence of a thermally induced sharp increase of thermoremanence around the Curie temperature of Invar-like Fe-Zr(B,Cu) soft magnetic glasses. Neutron-diffraction measurements indicate that a true enhancement of the average local[...]
