Barium ferrite Barium ferrite Barium ferrite, abbreviated BaFe, BaM, is the chemical compound with the formula BaFeO. This and related ferrite materials are components in magnetic stripe cards and loudspeaker magnets. BaFe is described as Ba(Fe)(O). The Fe centers are ferromagnetically coupled. This area of technology is usually considered to be an application of the related fields of materials science and solid state chemistry. Barium ferrite is a highly magnetic material, has a high packing density, and is a metal oxide. Studies of this material date at least as far back as 1931, and it has found applications in magnetic card strips,
Sterling v. Velsicol Chemical Corp. Furthermore, the trenches were neither lined nor covered with any impermeable material to prevent the chemical waste from leaking into the soil. Velsicol eventually placed a clay cap over the landfill site in 1980 only after state authorities threatened a lawsuit over the imminent danger the landfill posed to the environment. Sterling v. Velsicol Chemical Corp. Sterling v. Velsicol Chemical Corp., 855 F.2d 1188 (6th Cir. 1988), was an environmental lawsuit filed by citizens of Hardeman County, Tennessee, led by Steven Sterling, who sued Velsicol Chemical Corporation for contaminating their water supply through improper disposal of toxic chemicals.
