A theory of the magnetic induction bifurcation at a diamagnetic phase transition in normal metals is developed. Our results are in good agreement with the recent observation of the muon spin rotation resonance splitting in beryllium due to Condon domains, Solt et al. [Phys. Rev. Lett. 76, 2575 (1996); Hyperfine Interact. 104, 257 (1997)], being the first measurement of the onset of a diamagnetic phase transition. Temperature dependence of the order parameter, the magnetization in each Condon domain, is explained and reproduced quantitatively. A new kind of phase diagram for diamagnetic phase transitions is constructed.
