Numerical validation of quantum magnetic ordering

October 22nd, 2013 in Physics / Quantum Physics

A new study set out to use numerical simulations to validate previous theoretical predictions describing materials exhibiting so-called antiferromagneting characteristics. A recently discovered theory shows that the ordering temperature depends on two factors-namely the spin-wave velocity and the staggered magnetisation. The results, largely consistent with these theoretical predictions, have now been published in a paper in the European Physical Journal B by Ming-Tso Kao and Fu-Jiun Jiang from the National Taiwan Normal University, in Taipei.

In antiferromagnetic materials, the spins of electrons align in a regular pattern pointing in opposite directions to their neighbours. The materials' magnetic ordering conditions the , referred to as the Néel temperature, above which the macroscopic magnetic ordering is no longer present.
