A Possible Magnetic Structure of the Cluster-Based Haldane Compound Fedotovite K2Cu3O(SO4)3

We carried out neutron powder diffraction experiments on the cluster-based Haldane compound fedotovite K2Cu3O(SO4)3. Weak magnetic reflections caused by a magnetic long-range order appeared below an antiferromagnetic transition temperature TN =3.1 K. We propose a possible magnetic structure that is consistent with the magnetic properties reported in the literature.

Reduction of the Ordered Magnetic Moment by Quantum Fluctuation in the Antiferromagnetic Spin-5 2 Dimer Compound FeVMoO7

We investigated the magnetism of FeVMoO7 by performing magnetization, specific heat, electron spin resonance, and neutron diffraction experiments. We observed an antiferromagnetically ordered state below T_N = 10.8 K. We consider that the probable spin model is an interacting antiferromagnetic spin-5/2 dimer model where spin dimers are connected by interdimer interactions. The intradimer interaction was evaluated to be J = 10.5 +- 0.5 K. The magnitude of ordered magnetic moments is 4.00(7) mu_B at 4...
