Very low temperature specific heat of Al 5056

The transition temperature from normal to superconducting state and the specific heat of Al 5056 aluminium alloy in the 0 1 -3 6 K temperature range have been measured. This alloy is largely used in resonant detectors of gravitational waves A comparison with specific heat data of the same material obtained by different measuring methods is given.
