Magnetic structure of lightly doped cuprates
Glazman L. I. , Ioselevich A. S.
The effect of impurity magnetic states on the long-range order in a layered antiferromagnet has been studied. A magnetic phase diagram has been constructed for lightly doped La2 _ x Srx Cu04. The layered structure and the long-range effects shrink the antiferromagnetic region and give rise to a reentrant antiferromagnetic transition.
