Computed Normal Range of Iowa Statewide July Precipitation
Iowa summer rainfall distributions are examined to identify small-scale anomalies. Examination of extremely wet and dry summer months shows that large rain amounts fall mainly in small, cellular areas for both extremely wet and dry months. These configurations result from individual rainfall events. Analysis of the distribution of mean July rainfall across the state reveals significant anomalous wet and dry regions that contrast with the background, east-west rainfall gradient. Because of the skewed nature of summer rainfall distributions, the median value is used to represent a more realistic expected rainfall amount for any given year. Some parts of the stare have a more variable distribution and are more sensitive to the expected annual swing of one standard deviation. On the basis of statistical probabilities, these areas can expect summers of more severe moisture deficiencies to occur more often than in the rest of the stare
Room temperature magnetism in LaVO3/SrVO3 superlattices by geometrically confined doping
Based on the Hubbard model of strongly correlated systems, a reduction in the
bandwidth of the electrons can yield a substantial change in the properties of
the material. One method to modify the bandwidth is geometrically confined
doping, i.e. the introduction of a (thin) dopant layer in a material. In this
paper, the magnetic properties of LaVO/SrVO superlattices, in which the
geometrically confined doping is produced by a one monolayer thick SrVO
film, are presented. In contrast to the solid solution LaSrVO,
such superlattices have a finite magnetization up to room temperature.
Furthermore, the total magnetization of the superlattice depends on the
thickness of the LaVO layer, indicating an indirect coupling of the
magnetization that emerges at adjacent dopant layers. Our results show that
geometrically confined doping, like it can be achieved in superlattices,
reveals a way to induce otherwise unaccessible phases, possibly even with a
large temperature scale.Comment: 5 pages, 4 figure
