摘要
The magnetic structure of CuB2O4 is investigated by optical second harmonic generation. A rich second harmonic spectrum is observed and at least three different magnetic phases in the magnetic-field/temperature plane are revealed for magnetic fields applied along the principal axes of the compound. In the temperature ranges T<T-R and T-R<T<T-N (with T-R=10 K and T-N=21 K) antiferromagnetic phases without and with a weak spontaneous ferromagnetic component are observed, respectively. A static magnetic field supports the phase directly below T-N and finally suppresses the magnetic reorientation at T-R. (C) 2003 American Institute of Physics.
