Neutron Scattering, Magnetometry, and Quantum Monte Carlo Study of the Randomly-Diluted Spin-1/2 Square-Lattice Heisenberg Antiferromagnet
O. P. Vajk, M. Greven, P. K. Mang +1
We have successfully grown sizable single crystals of La_2Cu_{1-z}(Zn,Mg)_zO_4 with up to nearly half of the magnetic Cu sites replaced by non-magnetic Zn and Mg. Neutron scatterin…
Magnetic Properties and Phase Diagram of Li-doped La(2)CuO(4): Common Magnetic Response of Hole-doped CuO2 Planes
T. Sasagawa, P. K. Mang, O. P. Vajk +2
Although La(2)Cu(1-x)Li(x)O(4) [Li-LCO] differs from La(2-x)Sr(x)CuO(4) [Sr-LCO] in many ways (e.g., the absence of metallic transport, high-Tc superconductivity, and incommensurat…
Quantum vs. Geometric Disorder in a Two-Dimensional Heisenberg Antiferromagnet
O. P. Vajk, M. Greven
We present a numerical study of the spin-1/2 bilayer Heisenberg antiferromagnet with random interlayer dimer dilution. From the temperature dependence of the uniform susceptibility…
Quantum Impurities in the Two-Dimensional Spin One-Half Heisenberg Antiferromagnet
O. P. Vajk, P. K. Mang, M. Greven +2
The study of randomness in low-dimensional quantum antiferromagnets is at the forefront of research in the field of strongly correlated electron systems, yet there have been relati…
