Notes:
Dia- and paramagnetic (Condon) domains in simple metals, produced at low temperatures and in high magnetic fields via the cooperative effect of electrons in Landau orbitals, are observable by the muon spin rotation (μSR) technique. For beryllium, domains were seen for T〈3.5 K in fields 1〈H〈3 T through a well resolved splitting of the muon precession frequency, the split lines reappearing in each de Haas–van Alphen (dHvA) period as the applied field H varies. The beat in the dHvA oscillations allowed varying of the amplitude χ0 of the differential susceptibility, the key parameter determining domain properties. The data points in the (B,T) plane show that the standard formula for χ0(B,T) fails to describe the phase diagram, a consequence of the nearly cylindrical Fermi surface of Be. For white tin, preliminary data indicate the presence of domains by the oscillatory behavior of the μSR linewidth at T=0.1 K in fields of H(approximate)1 T, arising from electrons in the pocket of the Fermi surface in the sixth zone. © 2000 American Institute of Physics.
