## Title

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

## Description

- description: "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 \r\nJ = 10.5 +- 0.5 K. The magnitude of ordered
    magnetic moments is 4.00(7) mu_B at 4 K.  The magnitude at 0 K is considered to
    be smaller than the classical value 4.95 mu_B (g=1.98). We confirmed a reduction
    of ordered magnetic moments by quantum fluctuation in high-spin (spin-5/2) clusters
    as known in high-spin chains. "
