Interplay between SDW and induced local moments in URu2Si2
V. P. Mineev, M. E. Zhitomirsky
Theoretical model for magnetic ordering in the heavy-fermion metal URu2Si2 is suggested. The 17.5K transition in this material is ascribed to formation of a spin-density wave, whic…
Dzyaloshinsky-Moriya-Induced Order in the Spin-Liquid Phase of the S=1/2 Pyrochlore Antiferromagnet
Valeri N. Kotov, Maged Elhajal, Michael E. Zhitomirsky +1
We show that the S=1/2 pyrochlore lattice with both Heisenberg and antisymmetric, Dzyaloshinsky-Moriya (DM) interactions, can order antiferromagnetically into a state with chiral s…
Exact low-temperature behavior of kagome antiferromagnet at high fields
M. E. Zhitomirsky, Hirokazu Tsunetsugu
Low-energy degrees of freedom of a spin-1/2 kagome antiferromagnet in the vicinity of the saturation field are mapped to a hard-hexagon model on a triangular lattice. The latter mo…
Magnetocaloric effect in one-dimensional antiferromagnets
M. E. Zhitomirsky, A. Honecker
An external magnetic field induces large relative changes in the entropy of one-dimensional quantum spin systems at finite temperatures. This leads to a magnetocaloric effect, i.e.…
