The magnetic properties of multiferroic BaCoF4

The magnetic properties of multiferroic BaCoF4

Multiferroic barium cobalt fluoride, BaCoF4, has been prepared by hydrothermal method. The antiferromagnetic structure has been confirmed, and the possible weak ferromagnetism due to Dzyaloshinskii-Moriya interaction has been excluded, from the straight line shape of applied magnetic field dependent...
