Abstract

We report on the structure and physical properties of a bidimensional chromate, Sr4Cr3O10, the n=3 member of the Ruddlesden-Popper Srn+1CrnO3n+1 series. For the first time, using complementary x-ray powder diffraction and electron diffraction data, we have solved its layered crystallographic structure. Our study shows also that this high pressure phase is insulating and antiferromagnetic below TN=280K, a similar behavior already observed for n=1, 2 and n=+∞ members.
