2019-12-16 Colorant additions from Left to right: Neodymium Oxide, erbium oxide, and praseodymium oxide. The three rare earth metals that produce significant visible color are neodymium, erbium, and praseodymium. These have been shown to have intense color results in high-temperature firings, but have not been widely adapted for cone 6 oxidation.

The occurrences of rare metals on the shatter cone surfaces might be the result of recent (or subrecent) contamination either in the laboratory or in the field. Hundreds of small aggregates of native gold, as well as dispersed individual Au particles of up to 20 µm in size occur on the surfaces of some shatter cones.

The transverse-spin-wave dispersion relation and neutron-scattering cross section for strongly anisotropic magnets is formulated in terms of effective renormalized exchange and anisotropy parameters. The spin-wave dispersion for the cone structure is considered in detail, including a diagonalization of off-diagonal wave-vector-dependent terms and renormalization effects caused by the crystal ...
