Title: Dzyaloshinskii-Moriya interaction and the magnetic ground state in magnetoelectric ${LiCoPO}_{4}$

Abstract

Magnetic structures are investigated by means of neutron diffraction to shine light on the intricate details which are believed key to understanding the magnetoelectric effect in LiCoPO₄. At zero field, a spontaneous spin canting of φ = 7(1)° is found. The spins tilt away from the easy b-axis towards c. Symmetry considerations lead to the magnetic point group m$$'\atop{z}$$ which is consistent with the previously observed magnetoelectric tensor form and weak ferromagnetic moment along b. For magnetic fields applied along a, the induced ferromagnetic moment couples via the Dzyaloshinskii- Moriya interaction to yield an additional field-induced spin canting. An upper limit to the size of the interaction is estimated from the canting angle.

Magnetic order, hysteresis, and phase coexistence in magnetoelectric ${LiCoPO}_{4}$

Journal Article Fogh, Ellen ; Toft-Petersen, Rasmus ; Ressouche, Eric ; ... - Physical Review B

Here, the magnetic phase diagram of magnetoelectric LiCoPO₄ is established using neutron diffraction and magnetometry in fields up to 25.9T applied along the crystallographic b axis. For fields greater than 11.9T, the magnetic unit cell triples in size with propagation vector Q = (0,1/3,0). A magnetized elliptic cycloid is formed with spins in the (b,c) plane and the major axis oriented along b. Such a structure allows for the magnetoelectric effect with an electric polarization along c induced by magnetic fields applied along b. Intriguingly, additional ordering vectors Q ≈ (0,1/4,0) and Q ≈ (0,1/2,0) appear for increasing fields inmore »« less

Canted antiferromagnetic order and spin dynamics in the honeycomb-lattice compound ${Tb}_{2} {Ir}_{3} {Ga}_{9}$

Journal Article Ye, Feng ; Morgan, Zachary ; Tian, Wei ; ... - Physical Review B

Single-crystal neutron diffraction, inelastic neutron scattering, bulk magnetization measurements, and first-principles calculations are used to investigate the magnetic properties of the honeycomb lattice Tb2Ir3Ga9. While the R ln 2 magnetic contribution to the low-temperature entropy indicates a J(eff) = 1/2 moment for the lowest-energy crystal-field doublet, the Tb3+ ions form a canted antiferromagnetic structure below 12.5 K. Due to the Dzyaloshinskii-Moriya interactions, the Tb moments in the ab plane are slightly canted towards b with a canted moment of 1.22 mu(B) per formula unit. A minimal xxz spin Hamiltonian is used to simultaneously fit the spin-wave frequencies along the high-symmetrymore »« less

Dzyaloshinskii-Moriya interaction induced magnetoelectric coupling in a tetrahedral molecular spin-frustrated system

Journal Article Yu, Jie-Xiang ; Chen, Jia ; Sullivan, Neil ; ... - Physical Review. B

We have investigated magnetoelectric (ME) coupling in the single-molecule magnet Mn₄Te₄(PEt₃)₄ with tetrahedral spin frustration. Our density functional studies found that an electric dipole moment can emerge with various noncollinear spin orderings. The forms of spin-dependent dipole are determined and consistent with that in noncentrosymmetric magnets driven by the Dzyaloshinskii-Moriya interaction. Writing a parameterized spin Hamiltonian, after solving for eigenvalues and eigenstates, we quantified the ME coupling by calculating the thermal average of the electric and magnetic susceptibilities, which can be influenced by external magnetic and electric fields, respectively. The quadratic relations are expected to be observable in experiments.

Influence of chemical composition and crystallographic orientation on the interfacial magnetism in $BiFe O_{3}$ / $L a_{1 - x} S r_{x} Mn O_{3}$ superlattices

Journal Article Guo, Er-Jia ; Roldan, Manuel A. ; Sang, Xiahan ; ... - Physical Review Materials

The emergence of magnetism unique to the interface between the multiferroic BiFeO₃ (BFO) and ferromagnetic La_1-xSr_xMnO₃ (LSMO) offers an opportunity to control magnetism in nanoscale heterostructures with electric fields. Here, we investigate the influence of chemical composition and crystallographic orientation on the interfacial magnetism of BFO/LSMO superlattices. Our results reveal that the induced net magnetic moment in the BFO layers increases monotonically with increasing saturation magnetization of the LSMO layers. For the (100)-BFO/LSMO (x=0.2) superlattice, the induced moment reaches a record high value of ~2.8μ_B/Fe. No interfacial magnetization is observed at the (100)-BFO/LSMO interface when LSMO is an antiferromagnet. Inmore »« less
