“…Previous research has shown the effects of size of nanoparticles on thermodynamics of structural transition. Tveryanovich et al 14 obtained the nano-AgI with the thickness of the layers ranging from 10 to 100 nm using laser ablation and studied the structural transition of β to α with a Rigaku Ultima IV X-ray diffractometer, and they found that, with the decreasing size of nanoparticles, the temperature of the corresponding structural transition decreases. Xiao et al 15 performed a DSC test to investigate the structural transition of BaTiO 3 of different grain sizes, and the test results show that the structural transition enthalpy reduced with decreasing grain size.…”

Advances in the field of chemistry often involve nanoparticles, in which the structural transition is surprisingly different from the bulk material, and the difference between them is mainly attributed to the size of the nanoparticles. In this paper, tetragonal nano-CuFe 2 O 4 (t-CuFe 2 O 4 ) with different sizes ranging from 32 to 79 nm was prepared using the high temperature solid phase method. The structural transition of nano-CuFe 2 O 4 from tetragonal to cubic was determined by differential scanning calorimetry (DSC). The theoretical derivations and experimental tests indicate that, as the size decreases, the temperature, the enthalpy, and the entropy of the structural transition of nano-CuFe 2 O 4 decrease accordingly and present linear variation with the reciprocal of size, respectively. Furthermore, the effect of particle sizes on the magnetic properties of nano-CuFe 2 O 4 was investigated. The results show that the size of nano-CuFe 2 O 4 can obviously affect the magnetic properties: with the particle size of nano-CuFe 2 O 4 decreasing, the saturated magnetic induction decreases, the coercivity increases, while the remanence decreases.
