Abstract
Nuclear quadrupole resonance (NQR) is well known radiofrequency spectroscopic method often used in study of structure and structural dinamics in solid state physics, but it offers some interesting applications on the other fields also. Due to the fact that the NQR spectra in some substances depend strongly on the temperature it can be used in thermometry and it is suitable for the secondary laboratory temperature standard. Improved measuring techniques enable the detection of NQR signals in extremely small samples which can be used as thermosensors. In some substances the size can be as low as 1/10 mm3 or even only few 1/100 mm3. The aim of the proposed project is the improvement of the NQR temperature measurement method and applicaton of it in some cases where the other techniques can not give the expected results.
