Description

The anomaly of unusual shape in the specific heat and the maximum in the derivative of the magnetic suseptibility dχ(T)/dT at around 6 K as well as magnetization behavior of the low dimensional Li2ZrCuO4 allude to onset of a long range order in this compound. This suggestion is also supported by results of muon spin relaxation performed on a powder sample of Li2ZrCuO4, which show a spontaneous muon spin precession below 5.75 K. A peculiar rectangular shape of the static field distribution in the ordered state is consistent with an incommensurate helical spin structure predicted theoretically. (orig.)
