(BEDT-TTF) 3 CuX 2 Br 2 , XCl or Br displays two magnetic transitions; one (T P ) associated with a loss of moments accounted for by two S=1/2 ions and the second to a long range (LRO) antiferromagnetic ordering (T N ). The experimental data in the paramagnetic regions have been modeled by the sum of two contributing components, the BEDT-TTF and the Cu(II), the first to a hexagonal layer of BEDT-TTF (S=1/2) where the ions dimerize at T P and the second to a triangular layer of Cu ions. A possible mechanism for the LRO-AF transition involving RKKY is proposed. BEDT-TTF copper layered magnetism [ABSTRACT FROM AUTHOR]
