Quantum critical phenomena in a spin- 12 frustrated square lattice with spatial anisotropy

چکیده
We present a model compound with spin-$\frac{1}{2}$ spatially anisotropic frustrated square lattice, in which three antiferromagnetic interactions and one ferromagnetic interaction are competing. observe an unconventional gradual increase the low-temperature magnetization curve reminiscent of quantum critical behavior between gapped gapless phases. In addition, specific heat electron spin resonance signals indicate one-dimensional characteristics. These results demonstrate associated dimensionalization caused by lattice.

Modified Spin Wave Thoery of the Bilayer Square Lattice Frustrated Quantum Heisenberg Antiferromagnet
The ground state of the square lattice bilayer quantum antiferromagnet with nearest and next-nearest neighbour intralayer interaction is studied by means of the modified spin wave method. For weak interlayer coupling, the ground state is found to be always magnetically ordered while the quantum disordered phase appear for large enough interlayer coupling. The properties of the disordered phase ...
متن کاملNematic order in square lattice frustrated ferromagnets.
We present a new scenario for the breakdown of ferromagnetic order in a two-dimensional quantum magnet with competing ferromagnetic and antiferromagnetic interactions. In this, dynamical effects lead to the formation of two-magnon bound states, which undergo Bose-Einstein condensation, giving rise to bond-centered nematic order. This scenario is explored in some detail for an extended Heisenber...
متن کاملMonte Carlo studies of critical phenomena in mixed spin-3/2 and spin-5/2 Ising model on square lattice
We used a Monte Carlo simulation to analize the magnetic behavior of Ising model of mixed spins S i = ±3/2,±1/2 and σ j = ±5/2,±3/2,±1/2, on a square lattice. Were studied the possible critical phenomena that may emerge in the region around the multiphase point (D/|J1| = −3, J2/|J1| = 1) and the dependence of the phase diagrams with the intensities of the anisotropy field of single ion (D/|J1|)...
متن کاملM ar 1 99 6 New valence bond crystal phase of a frustrated spin - 12 square lattice antiferromagnet
We propose a new type of magnetically disordered ground state for a frustrated quantum antiferromagnet. This disordered state is an array of spin singlets spontaneously formed on four spin plaquettes. Both perturbation results and bond-operator calculations show that this phase has lower energy than the columnar dimer state. Analysis of available numerical data on finite clusters also supports ...

In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4), ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...
