Light‐Modulated Exchange Bias in Multiferroic Heterostructures
Electron, EarlyView.In this article, exchange bias and magnetization are modulated with visible light at room temperature in PMN‐PZT/FeGa/IrMn multiferroic heterostructures. Photostrictive effect is the main mechanism leading to the modulation of magnetic anisotropy and interfacial exchange bias coupling between the ferromagnetic and antiferromagnetic layers.

Journal of Quaternary Science, EarlyView.ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Let's Talk About Bone Cylinders. Taphonomy of Carnivores and Humans
International Journal of Osteoarchaeology, EarlyView.ABSTRACTBone cylinders are a distinctive structure predominantly produced by durophagous carnivoran species during the consumption of long bones, in which the diaphyseal canal remains intact while both epiphyses are removed or consumed. This study evaluates the significance of this morphology, traditionally attributed to extant and extinct hyena ...

Oikos, EarlyView.Biodiversity is known to influence the performance of coexisting species and has been proposed as a management tool to enhance the resilience and functioning of plant communities under drought. However, experimental studies to disentangle the roles of phylogenetic and functional diversity as drivers of plant performance remain extremely scarce.

Photovoltaic Effect in a III‐IV‐V Compound Semiconductor
Progress in Photovoltaics: Research and Applications, EarlyView.A large reduction of the GaAs band gap is obtained with incorporation of 6.5% Ge during epitaxy without introducing extended defects or composition inhomogeneity. Heterojunction solar cell devices were fabricated with 0.76‐V open circuit voltage and an internal quantum efficiency above 40% at energies below the bandgap of the GaAs emitter.
