Abstract
The authors have measured the lattice thermal conductivity of very pure aluminium in the temperature range between 1.5K and 15K by suppressing the electronic thermal conductivity with a magnetic field in the Corbino geometry. Taking into account a linear term in the magnetoresistance in the extrapolation procedure, it is shown that the results are in excellent agreement with results obtained from alloying techniques and theoretical estimates.
