Title: Frustrated magnetism from local moments in FeSe

Abstract

We investigate properties of a spin-1 Heisenberg model with extended and biquadratic interactions, which captures crucial aspects of the low energy physics in FeSe. While we show that the model exhibits a rich phase diagram with four different magnetic ordering tendencies, we identify a parameter regime with strong competition between Néel, staggered dimer, and stripelike magnetic fluctuations, accounting for the physical properties of FeSe. We evaluate the spin and Raman responses using exact diagonalization. Through comparison with experiments we find enhanced magnetic frustration between Néel and collinear stripe ordering tendencies, which increases with increasing temperature. As a result, the explanation of these spectral behaviors with this frustrated spin model supports the idea of local spin interactions in FeSe.

Frustrated spin order and stripe fluctuations in FeSe

Journal Article Baum, A. ; Ruiz, H. N. ; Lazarević, N. ; ... - Communications Physics

Abstract The charge and spin dynamics of the structurally simplest iron-based superconductor, FeSe, may hold the key to understanding the physics of high temperature superconductors in general. Unlike the iron pnictides, FeSe lacks long range magnetic order in spite of a similar structural transition around 90 K. Here, we report results of Raman scattering experiments as a function of temperature and polarization and simulations based on exact diagonalization of a frustrated spin model. Both experiment and theory find a persistent low energy peak close to 500 cm ⁻¹ in B _{1 g} symmetry, which softens slightly around 100 K, that wemore »« less

Spin-orbit coupled $j_{eff} = 1 / 2$ iridium moments on the geometrically frustrated fcc lattice

Journal Article Cook, A. M. ; Matern, S. ; Hickey, C. ; ... - Physical Review. B, Condensed Matter and Materials Physics

We were motivated by experiments on the double perovskites La₂ZnIrO₆ and La₂MgIrO₆, such that our study of the magnetism of spin-orbit coupled j_eff = 1/2 iridium moments on the three-dimensional, geometrically frustrated, face-centered cubic lattice became our focus. Moreover, the symmetry-allowed nearest-neighbor interaction includes Heisenberg, Kitaev, and symmetric off-diagonal exchange. A Luttinger-Tisza analysis shows a rich variety of orders, including collinear A-type antiferromagnetism, stripe order with moments along the {111} direction, and incommensurate noncoplanar spirals, and we use Monte Carlo simulations to determine their magnetic ordering temperatures. Finally, we argue that existing thermodynamic data on these iridates underscores the presencemore »« less

Incommensurate correlations in the t - J and frustrated spin-1/2 Heisenberg models

Journal Article Moreo, A ; Dagotto, E ; Jolicoeur, T ; ... - Physical Review, B: Condensed Matter; (USA)

We analyze the possible existence of incommensurate correlations in the {ital t}-{ital J} model as a function of doping and in the {ital J}{sub 1}-{ital J}{sub 2}-{ital J}{sub 3} spin-1/2 Heisenberg model as a function of frustration using exact diagonalization techniques on small lattices. For the {ital t}-{ital J} model we found that when holes are introduced the spin structure factor {ital S}({bold q}) shifts the position of its maximum away from ({pi},{pi}). However, we do not observe indications of the existence of long-range incommensurate order. The frustrated Heisenberg model is analyzed using spin-wave techniques.

Quantum transitions of nematic phases in a spin-1 bilinear-biquadratic model and their implications for FeSe

Journal Article Hu, Wen-Jun ; Lai, Hsin-Hua ; Gong, Shou-Shu ; ... - Physical Review Research

Since its discovery, iron-based superconductivity has been known to develop near an antiferromagnetic order, but this paradigm fails in the iron chalcogenide FeSe, whose single-layer version holds the record for the highest superconducting transition temperature in the iron-based superconductors. The striking puzzle that FeSe displays nematic order (spontaneously broken lattice rotational symmetry) while being nonmagnetic, has led to several competing proposals for its origin in terms of either the 3d-electron's orbital degrees of freedom or spin physics in the form of frustrated magnetism. Here we argue that the phase diagram of FeSe under pressure could be qualitatively described by amore »« less
