Insulator-to-metal transition and large thermoelectric effect in La${}_{1-x}$Sr${}_x$MnAsO

Yunlei Sun, Jinke Bao, Chunmu Feng +2

We report the Sr substitution effect in an antiferromagnetic insulator LaMnAsO. The Sr doping limit is $x\sim$ 0.10 under the synthesis conditions, as revealed by x-ray diffraction…
