Copper(II) Carboxylates with 2,3,4-Trimethoxybenzoate and 2,4,6-Trimethoxybenzoate: Dinuclear Cu(II) Cluster and µ-Aqua-Bridged Cu(II) Chain Molecule

Magnetochemistry, 2021
Copper(II) complexes with 2,3,4-trimethoxybenzoic acid (H234-tmbz) and 2,4,6-trimethoxybenzoic acid (H246-tmbz), [Cu2(234-tmbz)4(H2O)2] (6) and [Cu(246-tmbz)2(µ-H2O)2(H2O)2]n (7), were synthesized and characterized by elemental analysis, infrared and UV ...

Effect of Dzyaloshinskii-Moriya Interaction on Heisenberg Antiferromagnetic Spin Chain in the Presence of a Longitudinal Magnetic Field

Tạp chí Khoa học Đại học Huế: Khoa học Tự nhiên, 2021
Using functional integral method for the Heisenberg antiferromagnetic spin chain with the added Dzyaloshinskii-Moriya Interaction in the presence of the longitudinal magnetic field, we find out expression for free energy of the spin chain via spin ...

2D-Perovskite Multiferroics: Interface-Induced Magnetoelectric Effect in Perovskite-Based Multiferroic Superlattices

Crystals, 2023
Multiferroics are materials crucial for energy-efficient scalable electronics. The implementation of an effective combination of ferroic orderings on the nanoscale requires the design of new multiferroic materials.

Antiferromagnetic interactions and the superconducting gap function [PDF]

Physical Review B, 1996
Spin-fluctuation-mediated superconductivity is conventionally associated with d_{x^2-y^2} pairing. We show that a generalized model of antiferromagnetic spin fluctuations in three dimensions may also yield a state with formal ``s-wave'' (A_{1g}) symmetry but with line nodes at k_z \approx \pm π/ 2c.

Strong band renormalization and emergent ferromagnetism induced by electron-antiferromagnetic-magnon coupling

Nature Communications, 2022
The interaction between antiferromagnetic magnons and electrons sits at the heart of many strongly correlated systems, however, investigation has been hampered by a lack of clear-cut examples.

Binuclear Nickel Complexes of a New Di(hydroxyphenyl)imidazolate

Magnetochemistry, 2022
Here, we report a new di(hydroxyphenyl)imidazolate ligand with an N2O2 donor set synthesized by a modified Debus–Radziszewski procedure. Its binuclear nickel(II) complexes feature a weak antiferromagnetic interaction with J12 = −3.16 cm−1 between the two

Antiferromagnetic interactions in Nd6Fe12Ga2-based compounds [PDF]

Physica B: Condensed Matter, 1995
Abstract It has been reported that antiferromagnetic coupling may exist between light-rare-earth and transition-metal ions in Nd 6 Fe 11 Ga 3 -type of compounds. In the present paper, the magnetic properties of Nd 6- x La x Fe 12 Ga 2 compounds with x = 0,1,2,3 have been studied by measuring the free-powder high-field magnetization at 4.2 K and

The complexity of antiferromagnetic interactions and 2D lattices [PDF]

Quantum Information and Computation, 2017
Estimation of the minimum eigenvalue of a quantum Hamiltonian can be formalised as the Local Hamiltonian problem. We study the natural special case of the Local Hamiltonian problem where the same 2-local interaction, with differing weights, is applied across each pair of qubits.
