Paper Abstract

We present an analytic expression for the point-function demagnetization tensor of equilateral triangular prism recording media made by nanosphere lithography. This result can be used to calculate the demagnetization field in the prism and may improve the precision in finite element micromagnetic models, especially for complex boundary geometric shapes. The corresponding demagnetization factors are calculated through the expression. The distribution of the demagnetization field is discussed at various aspect ratios with magnetization perpendicular to the triangle plane. It is found that the demagnetization field is enhanced in the vicinity of the surfaces and strongly depends on the aspect ratio.
