Abstract

The structures and properties of Ba0.7Sr0.3Ru1-xMnxO3 perovskites have been investigated in samples prepared at 1300 degrees C in air. Two polytypes are found, a 6H phase for 0.2 <= x <= 0.4 and a 4H type for 0.6 <= x <= 1. The cell parameters and volume vary linearly in both solid solution ranges. Spin-freezing transitions LIP to 60 K are observed for the 6H samples, but the 4H materials show high temperature Neel transitions at 210 to 280 K.
