INVESTIGATION OF MAGNETIC FRUSTRATION IN A(2)FEMO(6) (A=CA, SR, BA, M=NB, TA, SB) BY MAGNETOMETRY AND MOSSBAUER-SPECTROSCOPY

Abstract:

Perovskite-related compounds in the series A2FeMO6 (A=Ca, Sr, Ba; M=Nb, Ta, Sb) have been prepared using the standard techniques of solid state chemistry and characterized by X-ray powder diffraction, magnetometry and Mössbauer spectroscopy. All but the 6H hexagonal compound Ba2FeSbO6 adopt cubic or pseudo-cubic crystal structures and show a magnetic susceptibility maximum at ca. 25 K. Field cooled and zero-field cooled susceptibility data show a hysteresis below this maximum. The Mössbauer s...
