Calculate the magnetic anisotropy energy of a material with uniaxial anisotropy along the z-axis, given that the magnetization is oriented at an angle of 45 degrees with respect to the z-axis and the magnetic anisotropy constant is 1.5 x 10^-23 J. The volume of the sample is 2 x 10^-5 m^3 and the saturation magnetization is 8 x 10^5 A/m.
