Structure and magnetic properties of the pyrochlore Sc2Mn2O7
Abstract
Sc2Mn2O7 has been prepared at 60 kbar and the crystal structure has been determined from Rietveld analysis of x-ray powder diffraction data. A cubic pyrochlore structure is found described in space group Fd3m with a=9.5965(4) Å. Magnetic susceptibility data conform to the Curie-Weiss law in the range 175 K to 300 K with an effective moment of 3.6(1) μBMn and θp = +77(3) K indicating the predominance of ferromagnetic interactions. Nonetheless, …
