Crystal Acts Like a Two‐Dimensional Antiferromagnet

DOI: 10.1063/1.3035680

Gloria B. Lubkin

A single crystal of K2NiF4 acts like a two‐dimensional antiferromagnet above a critical temperature Tn = 97.1 K, according to a recent experiment at Brookhaven. At the critical temperature the crystal undergoes an extremely sharp phase transition to long‐range order in three dimensions. Then below that temperature the magnetization varies as (T−Tn)β where β = 0.15, again suggesting that the magnetic behavior is two dimensional.
