Exchange-bond structure and magnetization-step spectra of a diluted Heisenberg antiferromagnet on the square lattice: Lopsided two-exchange models
Yaacov Shapira, Valdir Bindilatti
Theoretycal results on the magnetization and susceptibility of a Heisenberg diluted antiferromagnet in the square lattice are given. The models considered have two exchange constan…
Magnetization steps and cluster-type statistics for a diluted Heisenberg antiferromagnet on the square lattice: Models with two exchange constants
Yaacov Shapira, Valdir Bindilatti
The paper presents theoretical results on the magnetization of a diluted Heisenberg antiferromagnet on the square lattice for models with two exchange constants (J1-J2 and J1-J3).…
Structure of Zn_(1-x)Mn_xIn_2Se_4 crystals grown by CVT
J. Mantilla, G. E. S. Brito, E. ter Haar +2
Single crystals of Zn_(1-x)Mn_xIn_2Se_4 were grown by the chemical vapour phase transport technique (CVT). The Mn concentration was varied from x=1 to x=0.01. Through X-rays powder…
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…
Eu-Eu exchange interaction and Eu distribution in Pb_(1-x)Eu_(x)Te from magnetization steps
Ewout ter Haar, Valdir Bindilatti, Nei F. Oliveira +6
The magnetization of Pb_{1-x}Eu_{x}Te samples with x = 1.9, 2.6 and 6.0% was measured at 20 mK in fields up to 50 kOe, and at 0.6 K in fields up to 180 kOe. The 20 mK data show the…
