Solar selective absorbers are very useful for photo thermal energy conversion. The absorbers normally consist of thin films (mostly composite), sandwiched between the antireflection layer and (base layer on) a metallic substrate, selectively absorbing in the solar spectrum and reflecting in the...

We study the ferrimagnetic properties of infinite multilayered A(nA)B(nB)-structure composed of two types of magnetic materials coupled with alternating antiferromagnetic interaction. The system is considered in the frame of an Ising model in the linear cluster approximation. The expression for...
