نویسندگان
چکیده
In Fe 2 Co Nb O 9 , magneto-electric ME poling induces below T N an electric polarization P whose magnitude increases with the magnetic field H . Large values and steep responses to are explained by a microscopic model based on random distribution of Co.

متن کاملAntiferromagnet on the Honeycomb Lattice
We study the q-state Potts antiferromagnet with q = 3 on the honeycomb lattice. Using an analytic argument together with a Monte Carlo simulation, we conclude that this model is disordered for all T ≥ 0. We also calculate the ground state entropy to be S0/kB = 0.507(10) and discuss this result. ∗email: [email protected] ∗∗email: [email protected] The effect of ground s...
متن کاملEquilibrium magnetization at the boundary of a magnetoelectric antiferromagnet.
Symmetry arguments are used to show that a boundary of a magnetoelectric antiferromagnet has an equilibrium magnetization. This magnetization is coupled to the bulk antiferromagnetic order parameter and can be switched along with it by a combination of E and B fields. As a result, the antiferromagnetic domain state of a magnetoelectric can be used as a nonvolatile switchable state variable in n...
متن کاملFrustrated honeycomb Heisenberg antiferromagnet: A Schwinger-boson approach.
We analyze the frustrated Heisenberg antiferromagnet defined on a honeycomb lattice using a Schwinger-boson mean-field theory. The spin-wave velocity and the susceptibility are presented as functions of the strength of the frustrating interaction for spin S = 12 , and the dynamic structure factor is calculated for various temperatures and frustrations. For large S, we find an increased Néel sta...
متن کاملNi3TeO6--a collinear antiferromagnet with ferromagnetic honeycomb planes.
We report a comprehensive study of magnetic properties of Ni(3)TeO(6). The system crystallizes in a noncentrosymmetric rhombohedral lattice, space group R3. There are three differently coordinated Ni atoms in the unit cell. Two of them form an almost planar honeycomb lattice, while the third one is placed between the layers. Magnetization and specific heat measurements revealed a single magneti...
