Abstract
The magnetisation of manganese stearate layers on aluminium foil has been measured between 20 K and 0.4 K. With the applied magnetic field parallel to the film we deduced an equivalent susceptibility of 6.4 x 10-3 4.2 K. This is close to our paramagnetic calculation based on the measured manganese spacing. Our results would be consistent with a transition to antiferromagnetism below 0.4 K.
