Field induced long-range-ordering in an S=1 quasi-one-dimensional Heisenberg antiferromagnet
arXiv:cond-mat/0006295 · doi:10.1103/PhysRevB.63.064420
Abstract
We have measured the heat capacity and magnetization of the spin one one-dimensional Heisenberg antiferromagnet NDMAP and constructed a magnetic field versus temperature phase diagram. We found a field induced long-range magnetic ordering. We have been successful in explaining the phase diagram theoretically.
