| Abstract: | ESR experiments on Ni(BrO3)26H2O were performed down to liquid helium temperatures, and the g-value, the magnitude and sign of the single-ion anistotropy parameter, and the strength of the Ni2+Ni2+ exchange interaction, were determined. The present data support a recent interpretation of the susceptibility data for this salt that assumes tetrahedral antiferromagnetism at very low temperatures. |
