Abstract: Magnetism and electrical resistance as a function of magnetic field, temperature, and chemical composition are studied in Cu oxides intercalated with metal phthalocyanines MPc, where M is Fe or Ni, and Pc is C_<32>H_<16>N_<8>. An unusually large positive magnetoresistance (MR) of ~ 1200% is observed in FePc-intercalated Bi_<2>Sr_<2>Ca_<n-1>Cu_<n>O_<2n+4> samples with two Cu-O layers in the unit cell (n=2). The magnitude of the MR decreased to 40% and ~ 0% in the FePc-intercalated n=3 and n=4 samples, respectively, and to ~ 300% in the NiPc-intercalated n=2 sample.
