Magnetic phase transition in a nanonetwork of solid (3)He in aerogel

Fisher formulated the idea for the experiment, which led to the first measurements of the magnetic properties of a nm-scale network of solid 3He atoms at ultralow temperatures. He devised a new cooling technique which employs the direct demagnetisation of 3He nuclei to enable access to a new low temperature regime. He compared and contrasted the observation of the magnetic phase transition to those previously measured in both bulk and 2-dimensional solid 3He, and he wrote the paper.
