Local spin resonance and spin-peierls-like phase transition in a geometrically frustrated antiferromagnet
Inelastic magnetic neutron scattering reveals a localized spin resonance at 4.5 meV in the ordered phase of the geometrically frustrated cubic antiferromagnet ZnCr2O4. The resonance develops abruptly from quantum critical fluctuations upon cooling through a first order transition to a co-planar antiferromagnet at T(c) = 12. 5(5) K. We argue that this transition is a three dimensional analog of ...
متن کاملFrustration-induced nanometre-scale inhomogeneity in a triangular antiferromagnet
Phase inhomogeneity of otherwise chemically homogenous electronic systems is an essential ingredient leading to fascinating functional properties, such as high-Tc superconductivity in cuprates, colossal magnetoresistance in manganites and giant electrostriction in relaxors. In these materials distinct phases compete and can coexist owing to intertwined ordered parameters. Charge degrees of free...
متن کاملN ov 1 99 4 RANDOM FRUSTRATION IN TWO - DIMENSIONAL SPIN - 1 / 2 HEISENBERG ANTIFERROMAGNET
The square lattice spin-1/2 antiferromagnet containing a dilute concentration, δ, of randomly placed ferromagnetic nearest-neighbor bonds is studied at low-temperature via nonlinear σ-model techniques and by exact diagonalization. We generally find that long-range Néel order is destroyed above a critical strength in the defective ferromagnetic exchange coupling-constant given by |Kc|/J ∼ δ . We...
متن کاملThe Two-Dimensional Quantum Heisenberg Antiferromagnet with Ising-Like Anisotropy
We study the two dimensional quantum Heisenberg antiferromagnet on the square lattice with easyaxis exchange anisotropy by the semiclassical method called pure-quantum self-consistent harmonic approximation. In particular, we focus on the problem of the existence of a nite-temperature transition in such a model, and study the corresponding critical temperature as the spin value and the anisotro...
متن کاملHoles in a Two–dimensional Quantum Antiferromagnet
A brief review is presented on the studies of the hole motion in a two–dimensional quantum antiferromagnet. An extended introduction is given to cover the background of the problem. The quantum Bogoliubov–de Gennes formalism which treats the local distortion of the spin configuration and the quantum renormalization process on an equal footing, is outlined. The latest development on the central ...
