We report on a possible onset of magnetism in F-substituted four-layered high-T c compounds Ba 2 Ca 3 Cu 4 O 8 (O 1Γy F y ) 2 (2y = 1.2, 1.4, 1.6 and 2.0) which are composed of two types of CuO 2 planes in a unit cell; two inner planes (IP's) and two outer planes (OP's). The Cu NMR study has reveale
