Anisotropic interactions in a Quantum Antiferromagnet Cs$_2$CuCl$_4$ as revealed by NMR.

ORAL

Abstract

We report nuclear magnetic resonance (NMR) measurements on the 2D frustrated quantum antiferromagnet Cs$_2$CuCl$_4$. $^{133}$Cs spectra at temperatures down to $60$\,mK and in external magnetic field up to $16$\,T are presented. We discuss the details of the destruction of the 3D long range ordered phases in this compound. The effects of temperature and the applied field are contrasted, that is, the details of the nature of the phase transition will be discussed. Furthermore, we will address the influence of anisotropic interactions on these phase transitions.
