Abstract

Sample of copper selenide Cu1.75Se was investigated using the NMR method. NMR 77Se in Cu1.75Se represents a single line with a width at half height of about 4 kHz. In the temperature range 200-450 K speed transverse and longitudinal relaxation times are equal (to within a margin of error). The main mechanism for averaging the dipole-dipole interaction is probably the movement of copper ions.
