Evidence for magnetic polarons in the magnetoresistive perovskites
Article Abstract:
Manganese perovskites based on the compound LaMnO(sub 3) are known for their unusual magnetic and electronic properties, particularly their 'colossal' magnetoresistance. This effect is suspected to be due to the presence of magnetic polarons. Through volume thermal expansion, magnetic susceptibility and small-angle neutron scattering measurements, the existence of magnetic polarons above the ferromagnetic ordering temperature, T(sub c) was proven.

A giant nucleopore protein that binds Ran/TC4
Article Abstract:
The protein RanBP2, which binds to the nuclear G protein Ran/TC4, contains 3,224 residues and is comprised of a leucine-rich amino-terminal region, four domains homologous to RanBP1, eight zinc-finger motifs and a carboxy terminus similar to cyclophilin. Studies show that RanBP2 is a part of the nuclear pore complex and is probably present on both sides of the pore. Ran/TC4 is necessary for the import of proteins containing NLS.

Infinite-layer iron oxide with a square-planar coordination
Article Abstract:
The formation of an infinite-layer iron oxide with square-planar oxygen coordination around the iron ion is discussed. The iron oxide compound is found to exhibit magnetic order at a very high temperature.
