Abstract
The exchange interaction in a famous antiferromagnetic linear chain system of CTS (copper tetra-amine sulfate, Cu(NH 3 ) 4 SO 4 H 2 O) was investigated using millimeter and newly developed submillimeter spin resonance techniques. The “intrachain” exchange interaction J was determined to J / k = 0.24±0.08 K which is less than one tenth of the exchange interaction to be expected from the linear chain model. The result shows that CTS can not be considered as a typical example of a linear chain antiferromagnet.Keywords
