    Notes: We performed a detailed study of the magnetization reversal in polycrystalline exchange-coupled NiO/Co bilayers over 10 decades of field sweep rate dH/dt for different NiO and Co thicknesses. For all sweep rates and thicknesses, the symmetry of the hysteresis loops shows that an identical pinning strength has to be overcome in both directions of the reversal. At low dH/dt the reversal is governed by domain wall displacement while domain nucleation is dominant at higher ones. The dH/dt at which the transition between the two regimes takes place depends on the relative thickness of the NiO and Co layers. It increases (decreases) when the Co (NiO) thickness is increased. Experimentally, it was found that the energy barrier varies linearly with the square root of the area corresponding to the activation (Barkhausen) volume which is consistent with a random walk model of the coupling between antiferromagnetic and ferromagnetic layers. The results can be explained in terms of a thermally activated switching of the NiO magnetization dragged by the Co reversal. © 2001 American Institute of Physics.

    Notes: Due to the collective nature of the electronic interactions responsible for the appearance of ferromagnetic ordering, a strong influence of reduced dimensionality is to be expected in ultrathin magnetic films and heterostructures. In this article we review a number of experimental results covering several of those effects. For instance, the coercivity of ultrathin Co/Cu(111) films increases continuously up to ∼6 monolayer Co thickness. We show that this behavior is related to the thickness dependence of the Curie temperature of these low-dimensional samples. Moreover, magnetic anisotropy and interlayer exchange coupling are also strongly affected by the structural features. Because of their smaller interfacial roughness, films grown with the aid of a surfactant Pb layer exhibit perpendicular magnetization up to larger thicknesses than those grown without Pb. With respect to the exchange coupling, the first ones show oscillatory magnetic coupling and complete antiferromagnetic coupling for both perpendicular and parallel magnetization between Co layers, while for films grown without Pb there is always some amount of ferromagnetic coupling between Co layers. © 2001 American Institute of Physics.

    Notes: Epitaxial films grown by coevaporation of Co and Cu on Cu(111) were investigated by low-energy electron diffraction and surface magneto-optical Kerr-effect measurements. The films are dominantly face-centered-cubic stacked up to high Co concentrations and exhibit ferromagnetism. Their coercivity is significantly reduced compared to pure Co films produced by thermal Co deposition on Cu(111) independent of the use of Pb as a surfactant. © 2000 American Institute of Physics.

    Notes: Abstract. Interlayer diffusion in epitaxial systems with a high energy barrier at the atomic steps – the so-called Ehrlich–Schwoebel (ES) barrier – is strongly reduced. As a consequence of this, a continuous accumulation of roughness takes place during growth. This undesirable effect can be corrected by using surfactant agents. We have studied the influence of the ES barrier on the preparation of epitaxial films on Cu(111), and the surfactant effect of a monolayer of Pb.

Growth plasticity in response to drought is geographically structured and linked to intraspecific variability in Pinus pinaster. Journal of Biogeography, 45(5), 1126-1139, https://doi.org/10.1111/jbi.13202

    Description: Aim: We investigate the effects of the environmental and geographical processes driving growth resilience and recovery in response to drought inMediterraneanPinus pinasterforests. We explicitly consider how intra-specific variability modulates growth resilience to drought. Location: western Mediterranean basin Methods: We analyzed tree rings froma large network of 48 forests (836 trees) encompassing wide ecological and climatic gradients and including six provenances. To characterize the major constraints of P. pinaster growth under extremely dry conditions, we simulated growth responses to temperature and soil moisture using a process-based growth model coupled with the quantification of climate-growth relationships.Then, we related growth-resilience indices to provenance and site variables considering different drought events. Results: P. pinaster displayed strong variation in growth resilience across its distributional range, but common patterns were found within each provenance. Post-drought resilience increased with elevation and drier conditions but decreased with spring precipitation. Trees from dry sites were less resistant to drought but recovered faster than trees from wet sites. Main conclusions: Resilience strategies differed among tree provenances: wet forests showed higher growth resistance to drought, while dry forests presentedfaster growthrecovery, suggesting different impacts of climate warming on forest productivity.We detected geographicallystructured resilience patterns corresponding to different provenances,confirming high intra-specific variability in response to drought. This information should be included in species distribution models to simulate forest responses toclimate warming and forecasted aridification.
