Magnetic Susceptibility Measurements for Polycrystalline [Ni(H_2O)_6](ClO_4)_2

摘要

The molar susceptibility of [Ni(H_2O)_6](ClO_4)_2 (powder) was investigated between 2-300 K using superconducting quantum interference.The magnetic moment of the sample was also measured at various magnetic strengths,until the sample became saturated.At low temperatures the sample shows an antiferromagnetic alignment.The effective magnetic moment connected with Ni~(2+) corresponds well with the value predicted by theory.No anomalous behavior of the molar susceptibility of [Ni(H_2O)_6](ClO_4)_2 was found at ca 225 K (as was previously stated by others authors).
