Absence of long-range order in K2Ni2(SO4)3

Abstract: In a vast majority of materials that contain a magnetic ion the interaction between magnetic moments residing on magnetic ions causes them to order in a particular fashion. The strength of the interaction typically determines the temperature (Tc, the critical temperature) below which the magnetic subsystem enters the long range ordered state with moments pointing along a given direction. There are rare examples where a particular geometrical arrangement of magnetic moments, for instance on a triangle where each spin pair wants to be in an up-down configuration, prevents the magnetic subsystem to achieve the ordered state and moments are found in a so-called spin-liquid phase, govern by quantum fluctuations. Preliminary results on K2Ni2(SO4)3 suggest that there is no order down to 100 mK. We want to perform the experiments with muons to confirm this hypothesis.
