Comprehensive study of the magnetic phase transitions in Tb3Co combining thermal, magnetic and neutron diffraction measurements

“…Thermal diffusivity has been obtained as a function of temperature from room temperature down to 30 K, paying special attention to the region around the magnetic transitions. This technique is very well suited to study the critical behavior in phase transitions and has been successfully applied to solid and liquid crystals (magnetic as well as ferroelectric transitions), including other intermetallic materials [19,[27][28][29][30][31][32][33][34][35], as it combines very low temperature rates (down to 5-10 mK/min) with a high sensitivity. The details of the experimental setup, as well as of the theory explaining how to extract the thermal diffusivity from the photopyroelectric signal, can be found elsewhere [29,36].…”

Critical behavior of the ferromagnetic transition in GdSc(Si,Ge) intermetallic compounds

“…Both thermal diffusivity and specific heat have been obtained for each of the four samples as a function of temperature in the region around the Curie temperature. This technique is very well suited to study the critical behavior in phase transitions and has been successfully applied to liquid crystals and solids (magnetic as well as ferroelectric transitions), including other intermetallic families [24][25][26][27][28][29][30][31][32]. The details of the experimental setup, as well as of the theory explaining how to retrieve the thermal variables from the photopyroelectric signal, can be found elsewhere [24,33].…”
