TL;DR: Experimental evidence for ferroelectricity arising from electron correlations in the triangular mixed valence oxide, LuFe2O4 is reported, and resonant X-ray scattering measurements are used to determine the ordering of the Fe2+ and Fe3+ ions.

TL;DR: A polaron ordered phase in low-doping rate is found and the polaron lattice seems to have the tendency to lock into this commensurate structure within a finite concentration range around the nominal value of 0.125.

TL;DR: In this article, a single-crystal synchrotron x-ray diffraction measurements in strong magnetic fields have been performed for magnetoelectric compounds and it has been found that the ferroelectric phase induced by the application of a magnetic field at low temperatures is characterized by commensurate lattice modulation along the orthorhombic $b$ axis with $q=1∕2$ and $q = 1∕4$.

TL;DR: In this article, the magnetic structure of the kagom\'e lattice antiferromagnet potassium jarosite (K jarosite) was examined by means of powder neutron diffraction.

TL;DR: In this article, the magnetic properties of perovskite-type compounds La1−xSrxCrO3 (x=0, 0.05,0.20, and 0.25) were measured from 4.5 K to 320 K. The initial magnetization curve indicates the existence of the metamagnetic property below 20 K.
