Establishing  NMR in High Magnetic Field Gradients (PFG-NMR, E-NMR) in the Field of Solid State Ionics

The first Anti-Helmholz coil designed  for producing high and short magnetic field gradient pulses (up to 5000 G/cm and less than 1 ms) in Pulsed-Magnetic-Field-Gradient and Electrophoretic NMR experiments.

Disassembled NMR high-T probe-head for insertion into the gradient coil. Insert for electrophoretic NMR is shown (second from the right).
