Angular magnetoresistance of the filled skutterudite compound CeOs4Sb12 has been investigated along the [110] direction. Distinct differences between the angular magnetoresistance data at T=0.55 K and 4.2 K coincide with a developing of spin-density waves at T ≈ 1.7 K in B = 5 T. Magnetoresistance experiments have been performed on a self-made assembly utilizing a commercial piezoelectric rotator.
