  • Magnetism in multiferroic ▫${\rm Pb_5Cr_3F_{19}}$▫
    Blinc, Robert ...
    We report on the first observation of a magnetic transition in multiferroic ▫${\rm Pb_5Cr_3F_{19}}$▫. The system undergoes a ferroelectric transition at ▫$T_C$▫ = 545 K and probably an ... antiferromagnetic transition around ▫$T_N$▫ = 11 K. Between 50 K and ▫$T_N$▫, the system is not paramagnetic but shows the presence of correlated spin clusters, indicating a superparamagnetic or spin glass state. The observable changes of the magnetic properties ongoing through ferroelectric phase transition show a magnetoelectric coupling that may be important for new devices.
