摘要：

This work studies the resonant behavior of nanoscale magnetic materials. This behavior, henceforth referred to as magnetostatic resonance, occurs at frequencies where the permeability is negative and the particle is much smaller than the wavelength. A surface integral equation is formulated on the boundary of the particle to calculate the resonance frequencies and modes. Unique physical properties of these resonances such as scale invariance of resonance frequency and orthogonality properties of resonant modes are studied. A numerical technique is presented to calculate the magnetostatic resonance frequencies of an arbitrary shape. Possible applications of these phenomena are outlined.
