Abstract

Anisotropic g-values and 1.590 THz antiferromagnetic gap of multiferroic material CuO has been observed for the first time using the advantages of THz high field ESR. Especially antiferromagnetic resonance measurements have been performed at 4.2 K for three principal axes up to 1.852 THz and 40 T, and the magnetic anisotropy of CuO will be discussed.
