Berezinskii-Kosterlitz-Thouless transition The transition is driven by unbinding of vortex pairs. The correlation length ξ and the in-plane susceptibility  diverge exponentially The correlation functions of the fluctuations of the in-plane spin components decay exponentially above T BKT and with power law below T BKT. for ( at ) Department of Structure Research of Condensed Matter

 A unique quasi-2D molecular magnet was designed.  The entropy of magnetic transition amounts to only 15% of the maximal expected value, which indicates a well-established state of short-range order above the transition temperature.  There is strong easy-plane anisotropy in the system.  Metamagnetic behavior with critical field of 100 Oe.  The scaling analysis of the critical region indicates that the transition might be of the Berezinskii-Kosterlitz-Thouless type.  The exponent beta for the local fields found by μSR technique is as expected for the BKT transition.
