Field-Tunable Berezinskii-Kosterlitz-Thouless Correlations in a Heisenberg Magnet

“…So far, experimental efforts to probe a genuine BKT transition in a bulk material were compromised by the onset of 3D order [12][13][14][15][16][17][18] due to the inherent 3D nature of these materials. Still, if the perturbative terms relative to a purely 2D XY model are small enough, the experimental observation of magnetic properties associated with BKT correlations may be possible in the transition regime [19][20][21][22][23].…”
