## Description

- description: We performed inelastic neutron scattering (INS) experiments on KCu4P3O12
    powder and compared the experimental results with those calculated for the spin
    model (an eight-spin zigzag chain with S = 1/2 ) using the data-driven technique
    based on machine learning. We observed magnetic excitations at approximately 3.0,
    4.1, 5.9, and 8.8 meV at 5.5 K and at approximately 3.8 and 5.9 meV at 49 K. The
    excitations corresponding to 3.0, 4.1, and 8.8 meV were magnetic excitations from
    the ground state to the first, second, and fourth excited states (2.87, 4.23,
    and 8.53 meV from the calculations), respectively. The excitations corresponding
    to 3.8 and 5.9 meV were magnetic excitations from the first excited state to the
    third and fourth excited states (3.78 and 5.67 meV from the calculations), respectively.
    An excitation was likely to exist between the first and second excited states
    at approximately 1.35 meV in the experimental results. The excitation energies
    obtained from the INS experiments were almost consistent with those calculated
    from the exchange interaction values via the data-driven technique. This consistency
    indicates that the data-driven technique is a powerful tool for evaluating multiple
    exchange interactions.
