Barium ferrite - Wikipedia

Barium ferrite, abbreviated BaFe, BaM, is the chemical compound with the formula BaFe 12 O 19. This and related ferrite materials are components in magnetic stripe cards and loudspeaker magnets. BaFe is described as Ba 2+ (Fe 3+) 12 (O 2−) 19. The Fe 3+ centers are ferromagnetically coupled.

undoped strontium-barium hexaferrite decreases by the substitution of rare-earth ions and it slightly increases for the 4f2 site. The variation of hyperfine magnetic field with dopant content of RE-Ni ions is akin to the compositional variation of saturation magnetization of RE-Ni doped strontium-barium hexaferrites. The results of the study

Barium - Wikipedia

Omstreeks 1500 werden bariumsulfaat bevattende stenen magische krachten toegekend, omdat ze een lichte gloed afgaven na te zijn verhit in aanwezigheid van houtskool. Zelfs na enkele jaren bleven de stenen in het donker nog nagloeien. Tegenwoordig staat dit verschijnsel bekend als fosforescentie.

Strontium - Wikipedia

Strontium komt via verwering terecht in het grondwater en vervolgens via de voedselketen in de botten en het tandglazuur van levende wezens. Doordat tandglazuur tijdens de kinderjaren wordt gevormd en daarna onveranderd blijft, geeft de strontiumverhouding in het glazuur een indicatie van de regio waarin een individu is opgegroeid.
