Abstract |
We have investigated the finite temperature magnetic ordering in the quasi-two-dimensional Heisenberg antiferromagnetic system (CnH2n+1NH3)2MnCl4 with various chain lengths n. Our results far the transition temperatures and the exchange energies for long chain compounds are in marked contrast to previous expectations. |
