Abstract

1998 dielectric properties, magnetic properties dielectric properties, magnetic properties D 9000 -018Preparation, Structure, and Magnetic Properties of the Alkaline Earth Manganese Compounds AMnX with A: Mg, Ca, Sr, Ba and X: Si, Ge, Sn.-The new compounds MgMnGe, MgMnSn, CaMnSi, CaMnSn, and SrMnSn are prepared by reaction of the elements. They crystallize tetragonally with the anti-PbFCl-type structure (space group P4/nmm, Z = 2), established by single crystal investigations. Magnetic measurements at 4.2-800 K indicate metamagnetic behavior at low temperatures. -(DASCOULIDOU, A.; SCHUCHT, F.; JUNG, W.; SCHUSTER, H.-U.
