Contribution

It demonstrates the propagation and interference of spin waves in Ising ferromagnets and links interference patterns to spin flip statistics, providing new insights into magnetic dynamics.

Findings

Interference patterns follow classic wave interference rules.

Destructive interference correlates with increased spin flips.

Interference effects vary with temperature.

Abstract

The spin wave interference is studied in two dimensional Ising ferromagnet driven by two coherent spherical magnetic field waves by Monte Carlo simulation. The spin waves are found to propagate and interfere according to the classic rule of interference pattern generated by two point sources. The interference pattern of spin wave is observed in one boundary of the lattice. The interference pattern is detected and studied by spin flip statistics at high and low temperatures. The destructive interference is manifested as the large number of spin flips and vice versa.
