Exchange bias associated with phase separation in the Nd₂/₃Ca₁/₃MnO₃ manganite
The exchange bias (EB) phenomenon has been found in Nd₂/₃Ca₁/₃MnO₃ perovskite. The phenomenon manifests itself as a negative horizontal shift of magnetization hysteresis loops. The EB phenomenon is evident of an interface exchange coupling between coexisting antiferromagnetic (AFM) and ferromagnetic...

| description |
The exchange bias (EB) phenomenon has been found in Nd₂/₃Ca₁/₃MnO₃ perovskite. The phenomenon manifests itself as a negative horizontal shift of magnetization hysteresis loops. The EB phenomenon is evident of an interface exchange coupling between coexisting antiferromagnetic (AFM) and ferromagnetic (FM) phases and
confirms the phase separated state of the compound at low temperatures. The EB effect is found to be strongly dependent on the cooling magnetic field and the temperature, which is associated with the evolution of spontaneous AFM–FM phase separated state of the compound. Analysis of magnetic hysteresis loops has shown that ferromagnetic moment MFM originating from the FM clusters saturates in a relatively low magnetic field about H ∼ 0.4 T. The obtained saturation value MFM (1 T) ∼ 0.45 µB is in a good agreement with our previous neutron diffraction data.
