Submillimeter Electron Spin Resonance. II Megagauss Magnets and ESR in CuCl₂2H₂O

Abstract

The multi-layer magnets based on the theory described in Part I were made and the maximum field was 1.07 MOe in a space of 2 mm in diameter with 5 mm in length. The submillimeter spin resonance in CuCl₂2H₂O was done using HCN laser and the exchange interaction J′ between dissimilar spins was determined as J′⁄k=0.67±0.08K. Compared to the main exchange value J between similar spins, J′⁄J=0.13±0.02 was obtained.
