Magnetic and dielectric properties of (CHAn)2MCl4 and (An)2MCl4, where M=Cu or Mn, CHAn=4-cyclohexyl analinium and An=analinium

The magnetic susceptibility χM and the relative permittivity εr' for (CHAn)2MnCl4, (An)2MnCl4, (CHAn)2CuCl4 and (An)2CuCl4, where CHAn=4-cyclohexyl analinium and AN=analinium ions have been studied in the temperature range of 80-400 K. The results showed antiferromagnetic character for the Mn-compounds and ferromagnetic character for Cu-compounds. The plots of εr'-T and χM-T showed some breaks attributed to dynamic disordering of the organic chains. The results were correlated and discussed in view of the composition as well as the structure of the compounds
