Abstract
An antiferromagnetic-resonance investigation is reported at low-temper atures in Zn-doped spin-Peierls compounds CuGeO3. The results are fitt ed to classical-antiferromagnetic-resonance theory with orthorhombic a nisotropy. The relevant parameters of the ground state, including the Neel temperature, the spin-flop field, and the temperature dependence of the zero-field excitation energy (lower mode), are deduced. A compa rison with the magnetic properties determined in an ultrasonic experim ent is also made.
