Experimental facility. Apparatus for the application of (electro-) magnetic fields. Lx1, 2, Ly1, 2 and Lz1, 2 are coils which enable directed EMF and the compensation of environmental fields. The accessory coil La is used in some experiments to generate a magnetic field gradient. For experiments at a fixed field strength, the sample (S) is centrally placed, for gradient experiments different locations in Y-direction samples were placed at locations along the middle axis (not shown). The samples were kept in a thermic insulation box (T) and temperature is controlled by a small heat exchanger built with copper pipes (Cu) driven by a water bath.
