Sažetak
Combining the ferroelectric and magnetic components into the solid solution it is expected to obtain the magneto-electric multiferroic material. Novel bulk ceramic compounds xPZT+(1-x)PFW (PZT=Pb(Zr_{; ; 0.53}; ; Ti_{; ; 0.47}; ; )O_{; ; 3}; ; , PFW=Pb(Fe_{; ; 2/3}; ; W_{; ; 1/3}; ; )O_{; ; 3}; ; ) for x=0.15, 0.20, 0.25, 0.50, 0.70, 0.80 were synthesized and their magnetic investigation was performed, including the measurement of zero-field cooled (ZFC) and field-cooled (FC) magnetization curves, magnetic hysteresis loops and a.c. susceptibility. In the low temperature region (below 20K) the splitting between ZFC and FC curves together with the peaks in a.c. susceptibility course point to the blocking/freezing of magnetic moments and magnetic relaxor-like behaviour. The glassy freezing approach to the shift of the susceptibility peaks with frequency gives the activation energies that exhibit a maximum around x=0.5. This is in agreement with the behaviour of blocking/freezing temperatures.
