Popis:	The influence of magnetic field and temperature on Abrikosov fluxoid pinning in supersaturated Al-10 at % Ag solid solution is investigated by the torque measurement method. The minimum rotation angle of the magnetic field for the breakaway of fluxoids from pinning centres, logarithmic decrement of oscillation attenuation, and oscillation frequency of elastic suspension with the specimen are determined. The magnetic moment of the specimen is also calculated. It is shown that pinning increases with the decomposition of the alloy leading to the formation of γ1-phase lamels.
