Abstract:
EPR measurements on crystals of compressed tetragonal Rb2PbCu(NO2)6 and K2PbCu(NO2)6 subjected to uniaxial stress have been carried out at various temperatures. The results indicate that uniaxial stress can reorient the crystal axes in both compounds and that smaller stresses are required for Rb2PbCu(NO2)6 than for K2PbCu(NO2)6 at comparable temperatures. Larger stresses are required at lower temperatures.
