Title: Long-range magnetic ordering of quasi-one-dimensional S=1/2 Heisenberg antiferromagnet Sr{sub 2}Cu(PO{sub 4}){sub 2}

Abstract

Magnetic properties of quasi-one-dimensional S=1/2 Heisenberg antiferromagnet Sr{sub 2}Cu(PO{sub 4}){sub 2} were investigated by temperature and field dependence of AC susceptibility down to 0.03K. A sharp peak was observed at T{sub N}=0.085K on the temperature dependence of AC susceptibility indicating long-range magnetic ordering. Taking into account the exchange constant, J/k{sub B}=143K (Hamiltonian =J-bar S{sub i}S{sub i+1}), the ratio k{sub B}T{sub N}/J is 0.06%. Sr{sub 2}Cu(PO{sub 4}){sub 2} is, therefore, one of the best one-dimensional Heisenberg antiferromagnet known so far.
