Magnetic ordering of quasi-1 D S = 1/2 Heisenberg antiferromagnet Cu benzoate at sub-mK temperatures

Magnetic ordering of quasi-1 D S = 1/2 Heisenberg antiferromagnet Cu benzoate at sub-mK temperatures

We have measured the AC susceptibility of quasi-1D S = 1/2 Heisenberg antiferromagnet Cu benzoate at temperatures down to 0.2 mK. A sharp susceptibility peak is observed at 0.8 mK under an earth field. This fact indicates a 3D ordering of linear chains coupled by a weak magnetic interaction between...

Zusammenfassung:We have measured the AC susceptibility of quasi-1D S = 1/2 Heisenberg antiferromagnet Cu benzoate at temperatures down to 0.2 mK. A sharp susceptibility peak is observed at 0.8 mK under an earth field. This fact indicates a 3D ordering of linear chains coupled by a weak magnetic interaction between chains.
