## Description

- description: "High coercivity is an important property of permanent magnets for
    application in energy conversion devices. The Nd magnet, Nd2Fe14B, is a typical
    material. Because coercivity is a long-time relaxation phenomenon, which originates
    from a strong metastable magnetic state, it is difficult to estimate coercive
    field (coercive force) studying the time evolution dynamics simulation of a model
    with atomistic parameters under the limitation of the simulation time. In our
    recent study [M. Nishino et al., Phys. Rev. B 102, 020413(R) (2020)], we presented
    a method to estimate coercivity using a statistical method to extend the limitation
    of simulation time and evaluated appropriately the coercive field of a single
    grain of the Nd magnet. In the present study, we propose an alternative method
    to estimate coercivity more conveniently using the field-dependent survival (nonreversal)
    probability generated by a time evolution simulation under a field sweep.We demonstrate
    that the coercive field of the single grain can be estimated. In this method,
    not only coercive field but also the zero-field energy barrier and field for the
    zero-energy barrier can be estimated. We discuss detailed features of the estimation
    of these quantities.\r\n"
