Mean-field description of skyrmion lattice in hexagonal frustrated antiferromagnets
نویسندگان
چکیده
Simple mean-field approach for frustrated antiferromagnets on hexagonal lattices, aimed to describe the high-temperature part of temperature-magnetic field phase diagram, is proposed. It shown, that an interplay between modulation vector symmetry, Zeeman energy and magneto-dipolar interaction leads stabilization triple-$Q$ skyrmion lattice in a certain region diagram. Corresponding analytical expressions boundaries are derived. argued developed theory can be applied description diagram observed experimentally Gd$_2$PdSi$_3$ compound.

Spin-lattice coupling in frustrated antiferromagnets
We review the mechanism of spin-lattice coupling in relieving the geometrical frustration of pyrochlore antiferromagnets, in particular spinel oxides. The tetrahedral unit, which is the building block of the pyrochlore lattice, undergoes a spin-driven Jahn-Teller instability when lattice degrees of freedom are coupled to the antiferromagnetism. By restricting our considerations to distortions w...
متن کاملImpurity effects in highly frustrated diamond-lattice antiferromagnets
We consider the effects of local impurities in highly frustrated diamond-lattice antiferromagnets, which exhibit large but nonextensive ground-state degeneracies. Such models are appropriate to many A-site magnetic spinels. We argue very generally that sufficiently dilute impurities induce an ordered magnetic ground state and provide a mechanism of degeneracy breaking. The states that are selec...

متن کاملField-induced order and magnetization plateaux in frustrated antiferromagnets
We argue that collinearly ordered states which exist in strongly frustrated spin systems for special rational values of the magnetization are stabilized by thermal as well as quantum fluctuations. These general predictions are tested by Monte Carlo simulations for the classical and Lanczos diagonalization for the S = 12 frustrated square-lattice antiferromagnet.
متن کاملQuasiparticle excitations in frustrated antiferromagnets
We have computed the quasiparticle wave function corresponding to a hole injected in a triangular antiferromagnet. We have taken into account multi-magnon contributions within the self consistent Born approximation. We have found qualitative differences, under sign reversal of the integral transfer t, regarding the multi-magnon components and the own existence of the quasiparticle excitations. ...
