Two dimensional antiferromagnetic Heisenberg model in the presence of an external field — •Mu-Sung Yang1 and Karl-Heinz M"utter2 — 1Bergische Universit"at Wuppertal-GH FB 8 Gau"sstr. 20 42097 Wuppertal — 2Bergische Universit"at Wuppertal-GH FB 8 Gau"sstr. 20 42097 Wuppertal
We present numerical results on the zero temperature magnetization curve and the static structure factors of the two dimensional antiferromagnetic Heisenberg model in the presence of an external field. The impact of frustration is also studied.
