Magnetic phase transitions in the dilute antiferromagnet Co0.5Zn0.5F2
Bazhan A. N., Amin Ali Ya., Petrov S. V.
Single crystals of Co0 5Zn0 5F2 have been grown, and their magnetic properties have been studied at magnetic fields from 0 to 60 kOe and at temperatures from 1.7 to 20 K. At Τ <TN = 12.5 ±0.5 К these crystals have the properties of a uniaxial antoferromagnet with a strong Dzyaloshinskii interaction. The perpendicular magnetic susceptibility has an unusual temperature dependence in weak magnetic fields.
