Magnetization steps in Zn_(1-x)Mn_xO: Four largest exchange constants and single-ion anisotropy
X. Gratens, V. Bindilatti, N. F. Oliveira +4
Magnetization steps (MST's) from Mn pairs in several single crystals of Zn_(1-x)Mn_xO (0.0056<=x<=0.030, and in one powder (x=0.029), were observed. The largest two exchange consta…

Magnetization steps in a diluted Heisenberg antiferromagnetic chain: Theory and experiments on TMMC:Cd
A. Paduan-Filho, N. F. Oliveira, V. Bindilatti +2
A theory for the equilibrium low-temperature magnetization M of a diluted Heisenberg antiferromagnetic chain is presented. The magnetization curve, M versus B, is calculated using…
