e three physicists were convinced that there was a real effect. They weren't looking for superfluidity in particular, but rather an antiferromagnetic phase in solid helium-3.
             According to their predictions, this phase appeared to occur at a temperature below 2mK. In their first publication in 1972, they interpreted this effect as a phase transition. They did not completely agree with this hypothesis, but by further developing their technique they could, just a few months later, pinpoint the effect. They found there were actually two phase transitions in the liquid phase, one at 2.7mK and the second at 1.8mK.
             This discovery became the starting point of intense activity among low temperature physicists. The experimental and theoretical developments went hand-in-hand in an unusually fruitful way. The field was rapidly mapped out, but fundamental disco
