Abstracts

EN

The results of the heat capacity and elastic constant studies of Fe_{3-x}Zn_{x}O_{4} (x<0.04) series are reported. Adiabatic heat capacity measurements, performed on single crystals, show the clear change of the transition character from first order for low Zn content (x<0.012) to the higher order in 0.012
