“…Figure 18 To further characterize the spin dynamics of FM manganites when T → T C several groups have studied the spin diffuse scattering near T C [19,23,25,26,51,52,55,56]. An anomalous and field-dependent central diffusive component which develops above T ∼ 0.8T C for La 0.7 Ca 0.3 MnO 3 [25] and T ∼ 0.9 T C for Nd 0.7 Sr 0.3 MnO 3 [23] and dominates the fluctuation spectrum as T → T C [25,23] has been observed for the low-T C samples, coinciding with the non-collapse behaviour of D(T ).…”

Ferromagnetic (FM) manganites, a group of likely half-metallic oxides, are of special interest not only because they are a testing ground for the classical double-exchange interaction mechanism for the 'colossal' magnetoresistance, but also because they exhibit an extraordinary arena of emergent phenomena. These emergent phenomena are related to the complexity associated with strong interplay between charge, spin, orbital, and lattice. In this review, we focus on the use of inelastic neutron scattering to study the spin dynamics, mainly the magnon excitations in this class of FM metallic materials. In particular, we discuss the unusual magnon softening and damping near the Brillouin zone boundary in relatively narrow-band compounds with strong Jahn-Teller lattice distortion and charge-orbital correlations. The anomalous behaviours of magnons in these compounds indicate the likelihood of cooperative excitations involving spin and lattice as well as orbital degrees of freedom.

A recent vast experimental and theoretical effort in manganites has shown that the colossal magnetoresistance effect can be understood based on the competition of charge-ordered and ferromagnetic phases. The general aspects of the theoretical description appear to be valid for any compound with intrinsic phase competition. In high temperature superconductors, recent experiments have shown the existence of intrinsic inhomogeneities in many materials, revealing a phenomenology quite similar to that of manganese oxides. Here, the results for manganites are briefly reviewed with emphasis on the general aspects. In addition, theoretical speculations are formulated in the context of Cu-oxides by mere analogy with manganites. This includes a tentative explanation of the spin-glass regime as a mixture of antiferromagnetic and superconducting islands, the rationalization of the pseudogap temperature T * as a Griffiths temperature where clusters start forming upon cooling, the prediction of "colossal" effects in cuprates, and the observation that quenched disorder may be far more relevant in Cu-oxides than previously anticipated.

For governments, pre‐emptive strategies for handling communications and risk management have become essential for public perception, which plays such a significant part in structuring political responses to disaster and conflict. In an interview with guest‐editor Charles Rice, former US Secretary of Homeland Security Michael Chertoff highlights the importance of ‘lessons learnt’ and informed anticipation.
