Description
Specific heat and thermal expansion measured along the c-axis are reported for the UAsSe single crystals with TC=101.5 K , which display the pronounced low-T upturn in the electrical resistivity. Besides the ferromagnetic transition, no additional anomaly has been found that could affect the low- T physics of UAsSe. The investigated 77Se NMR spectra give evidence for a systematic development of the disorder caused by a small change of the sample composition. The appearance of electron-assisted tunneling of the atoms in UAsSe and related compounds is discussed. (author)
