Few studies have compared scales of heterogeneity among plant communities. We predicted that differences in the sizes of dominant species should allow us to detect small-scale (2 plots arranged in pairs separated by 0-256 cm. Several variables in pra

The crystal structure of La{sub 1.2}Sr{sub 1.8}Mn{sub 2}O{sub 7} has been determined as a function of temperature in magnetic fields of 0 and 0.6 T. There is a significant magnetostriction at the Curie temperature T{sub C}; the a axis contracts ({Del

In antiferromagnetic MnF2 the magnetic moments of manganese are aligned along the tetragonal axis of the rutile structure. In a magnetic field HSF along that axis (9.27 T at 4.2 K) the antiferromagnetic moments flop in the basal plane. Polarized neut

The miscibility gap of ${\mathrm{La}}_{2}$${\mathrm{CuO}}_{4+\mathrm{\ensuremath{\delta}}}$ was investigated by studying three electrochemically oxygenated samples with different oxygen contents, using variable-temperature neutron powder diffraction.

We have formed a resonant cavity for a massive particle, the neutron, in an attractive potential between a surface segregated polymer film and its substrate. Standing waves occur when incident waves interfere with the waves reflected from the substra

A brief description is given of the time-of-flight neutron reflectometer POSY II at the Intense Pulsed Neutron Source (IPNS) at Argonne National Laboratory. Both data collection and refinement of the experimental data are nearly automatic. The neutro

A current, widespread example of vegetation change is the invasion of grassland by woody plants. This is associated with an increase in soil heterogeneity, and it has been argued that woody plants both cause and benefit from high heterogeneity. We kn

Subtle pressure-induced structural changes in YBa2Cu3O6.93 and YBa2Cu3O6.60 have been measured by neutron powder diffraction for samples in a hydrostatic helium-gas pressure cell. Small, but significant, differences in the compression of particular C
