Anomalous Crystallinity and Magnetism in Chemically Disordered Coherent Heterostructures
Advanced Materials, EarlyView.Coherent isostructural high‐entropy oxide heterostructures are realized despite remarkable >5% interfacial lattice distortion. The resulting buried interface exhibits abrupt valence reconstruction which contributes to 2 × enhanced exchange bias in the heterostructure relative to constituent layers, demonstrating how chemical disorder enabled anomalous ...

Neutrons of thermal energies [PDF]
Proceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences, 1936 Abstract If fast neutrons, such as those emitted by beryllium under alpha-particle bombardment, are allowed to pass through a considerable bulk of material rich in hydrogen, they rapidly lose energy by collisions with protons, so that the neutrons present in the medium have energies which are, on the average, very much less than those
