Electronic Dissertations and Theses

The calorimetric properties of a CaEuZrO based sample, synthesized by a solid-state reaction process in the Electron Transport and Magnetic Properties of Materials (ETMPM) lab, are investigated by analyzing low temperature (2 -20 K) heat capacity data. The total heat capacity of a material may be expressed as C = Celec + Cph + Cnuc + Cmag + Ci. In mathematical terms, it may be expressed as C = yT + aT3 + An T-2 + Ci. In this equation, the term yT is the electronic heat capacity, aT3 is the lattice or phonon heat capacity, AnT-2 is the nuclear …
