Fizika Nizkikh Temperatur 43 (2017) 1482-1486 The magnetic moment in the superconducting and normal state of a crystalline
FeTe0.65Se0.35 superconductor, grown by the Bridgman's method with relatively
high growth rate, was measured. The temperature and magnetic field dependences
of magnetization and its relaxation time were determined. Studied crystal,
being non-uniform due to high growth rate of 5 mm/h, exhibits smaller width of
superconducting transition in comparison with an ideal crystal grown with
velocity of 1 mm/h, and the difference in magnetic properties of crystals grown
with various growth rate, related to their microstructure, is discussed.
