论文摘要

通过评估磁场下液滴的磁化,将边界条件与反向相匹配,并指出反相磁化是否持续,通过重新归一化组理论来计算亚稳态的逆相液滴。因此,在三维中,最大的亚稳态液滴大小和跨液滴边界的不连续性是根据ISING模型的场和温度的函数计算的。该方法还产生有限系统的磁滞回路,作为温度和系统尺寸的函数。

Metastable reverse-phase droplets are calculated by renormalization-group theory by evaluating the magnetization of a droplet under magnetic field, matching the boundary condition with the reverse phase and noting whether the reverse-phase magnetization sustains. The maximal metastable droplet size and the discontinuity across the droplet boundary are thus calculated as a function of field and temperature for the Ising model in three dimensions. The method also yields hysteresis loops for finite systems, as function of temperature and system size.
