(*) 
Returning to Leiden after the war, Gorter devoted much of his energy
to the transformation of the Kamerlingh Onnes Laboratory into a
cryogenic lab with modern electronic and instrumental equipment.
With his students D. de Klerk, M.J. Steenland, O.J. Poppema, W.J. Huiskamp,
H. Postma, and A.R. Miedema he began to investigate magnetism and
related subjects below 1 Kelvin by means of adiabatic demagnetization.
