The effect of deuteration on the magnetic critical temperatures of hydrogen-bonded materials
Keyword(s):
The change in the magnetic critical temperature caused by deuteration of the sample has been measured for two hydrated salts. For antiferromagnetic MnCl2∙4H2O, a shift in the Néel point of −2.3% was observed when 96% of the protons were replaced by deuterons. For ferromagnetic Cu(NH4)2Br4∙2H2O, the Curie point was shifted by +0.8% on deuteration. These results are compared with measurements on other materials and the results semiquantitatively explained by proposing an intimate relation between the superexchange interaction and the hydrogen bond strength.
