Spin Correlations and Magnetic Susceptibilities of Lightly Doped Antiferromagnets
F. Carvalho Dias, I. R. Pimentel
We calculate the spin correlation function and the magnetic longitudinal and transverse susceptibilities of a two-dimensional antiferromagnet doped with a small concentration of ho…
Destruction of long-range antiferromagnetic order by hole doping
F. Carvalho Dias, I. R. Pimentel, R. Orbach
We study the renormalization of the staggered magnetization of a two-dimensional antiferromagnet as a function of hole doping, in the framework of the t-J model. It is shown that t…
Magnetic Properties of Weakly Doped Antiferromagnets
I. R. Pimentel, F. Carvalho Dias, L. M. Martelo +1
We study the spin excitations and the transverse susceptibility of a two-dimensional antiferromagnet doped with a small concentration of holes in the t-J model. The motion of holes…
