Paramagnetic and antiferromagnetic resonances of powdered Cu0 are investigated. Very broad paramagnetic resonance with the y-value of about 2.0 is ob-served above T. at the 45 GHz region under pulsed magnetic field. The linewidth ismore than one Tesla and it is explained by the broadening due to the anisotropic exchange interaction between Cu" spins. One-dimensional spin correlation is seen inthe line profile. The zero field antiferromagnetic resonance is found by means of theinfrared absorption experiments in the temperature range between 5 K and 500 K.Two peaks at 350 and 510 cm ' with the width of about 100 cm ' are found. Theresult suggests that Cu0 might have a multisublattice structure even at low temperalures.[EPR, AFMR, one-dimensional antiferromagnet, infrared absorption, high ll magnetic field, pulse magnetl
