Key Points

Angular-dependent magnetization reversal occurred in circular and rectangular Permalloy nanorings, revealing key geometric effects.
Strongly interacting arrays increased the complexity of magnetization reversal, with significant results observed in measurements.
Magneto-optical Kerr effect measurements provided insights into the interplay of geometry and magnetic coupling.
Understanding these interactions may enhance the design of magnetic materials in technology applications.
