Abstract

At zero magnetic field, a series of five phase transitions occur in Co3 V2 O8. The Néel temperature, TN = 11.4 K, is followed by four additional phase changes at T1 = 8.9 K, T2 = 7.0 K, T3 = 6.9 K, and T4 = 6.2 K. The different phases are distinguished by the commensurability of the b-component of its spin density wave vector. We investigate the stability of these various phases under magnetic fields through dielectric constant and magnetic susceptibility anomalies. The field-temperature phase diagram of Co3 V2 O8 is completely resolved. The complexity of the phase diagram results from the competition of different magnetic states with almost equal ground state energies due to competing exchange interactions and frustration.
