We introduce Möbius functions of higher rank, a new class of arithmetic functions so that the classical Möbius function is of rank 2. With this idea, we evaluate Dirichlet series on the sum of the reciprocal square of all r-free numbers. For the proof, the Riemann zeta function and cyclotomic polynomials play a key role.
