A comparative study of the magnetic properties (magnetic moment, magnetocrystalline anisotropy) and hyperthermia response in Co-Zn spinel nanoparticles is presented. The CoxZn1-xFe2O4 nanoparticles (x = 1, 0.5, 0.4, 0.3, 0.2 and 0.1) were synthesized by co-precipitated method and the morphology and mean crystallite size (around 10 nm) of the nanoparticles were analysed by TEM Microscopy. Regarding the magnetic characterization (SQUID magnetometry), Co-Zn nanoparticles display at room temperature anhysteretic magnetization curves, characteristic of the superparamagnetic behavior. A decrease in the blocking temperature, TB, with the Zn content is experimentally detected that can be ascribed to the reduction in the mean nanoparticle size as x decreases. Furthermore, the reduction in the magnetocrystalline anisotropy with the Zn inclusion is confirmed through the analysis of TB versus the mean volume of the nanoparticles and the law of approach to saturation. Maximum magnetization is achieved for x = 0.5 as a result of the cation distribution between octahedral and tetrahedral spinel
Se presenta la perspectiva de género en la propuesta de dinamización que, desde el año 2008, desarrollamos en el yacimiento ibero de La Bastida de les Alcusses (Moixent, Valencia), y que se incluye dentro de un proyecto más amplio de gestión integral y sostenible de este bien patrimonial. Defendemos una visión inclusiva del género, rangos de edad y estatus y se argumenta que visualizar a las mujeres es un modo de empoderar, pero puede ser del todo insuficiente. Ponemos de manifiesto la dinámica vinculación entre valores de género, roles, gestos o técnicas corporales aprendidas socialmente, y ello a través de una interpretación honesta y seria del registro arqueológico.
