Dependence of exchange anisotropy and coercivity on the Fe–oxide structure in oxygen-passivated Fe nanoparticles

Ultrafine Fe particles have been prepared by the inert gas condensation method and subsequently oxygen passivated. The as-obtained particles consist in an Fe core surrounded by an amorphous Fe-oxide surface layer. The antiferromagnetic character of the Fe-oxide surface induces an exchange anisotropy in the ferromagnetic Fe core when the system is field cooled. Samples have been heat treated in vacuum at different temperatures. Structural changes of the Fe–O layer have been monitored by x-ray diffraction and transmission electron microscopy. Magnetic properties as coercivity, hysteresis loop shift, and evolution of magnetization with temperature have been analyzed for different oxide crystallization stages. A decrease of the exchange anisotropy strength is reported as the structural disorder of the surface oxide layer is decreased with thermal treatment

La ortodoxia de una heterodoxa: Teresa de Cartagena y la Biblia

This article examines the presence and use of biblical texts in the two works written by the 15th-century Castilian writer Teresa de Cartagena, Arboleda de los enfermos and Admiración Operum Dei. It also explores this in the wide context of the circles and currents of spiritual renovation that were active in late medieval and early modern Spain, especially those with a prominent female presence, and determines the affinities of the said author with such circles and currents.Examina este trabajo la presencia y uso de textos bíblicos en las dos obras de Teresa de Cartagena, autora castellana del siglo XV, Arboleda de los enfermos y Admiración Operum Dei, e inscribe estos usos literarios del texto bíblico en el contexto de los círculos y las corrientes de renovación espiritual, especialmente femenina, desarrollados en la península ibérica entre fines del siglo XV y comienzos del XVI, análisis que revela la afinidad de la mencionada autora con tales corrientes y círculos
