Surface antiferromagnetism and incipient metal-insulator transition in strained manganite films

F. Cossu, U. Schwingenschlögl, G. Colizzi +2

Using first-principles calculations, we show that the (001) surface of the ferromagnet La${}_{1-x}$Sr${}_x$MnO${}_3$ under epitaxial compression favors antiferromagnetic ordering in…
