Work
In 1936 he discovered
paramagnetic relaxation; however, he missed the discovery of
nuclear magnetic resonance (otherwise known as nuclear spin resonance), as described by
Joan Henri Van der Waals.
With
Hendrik Casimir
Hendrik Brugt Gerhard Casimir (15 July 1909 – 4 May 2000) was a Dutch physicist best known for his research on the two-fluid model of superconductors (together with C. J. Gorter) in 1934 and the Casimir effect (together with D. Polder) in 1 ...

The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water.

Gorter studied many aspects of
antiferromagnetism in
CuCl2·2H2O. With Johannes Haantjes, he developed a theoretical model of antiferromagnetism in a double-lattice substance. After WWII he worked on liquid
helium II and developed the theory which is now known as
Coulomb blockade, the increase in electrical resistance in metal films at low temperatures. The Gorter-Mellink equation describes the mutual friction of two fluids in liquid helium II.
