While tantalum (Ta) can set the magnetostriction toward the minus side, iron (Fe) sets the magnetostriction toward the plus side. In the case of an amorphous magnetic material containing both tantalum (Ta) and iron (Fe), it is therefore easy to adjust the absolute magnetostriction value to 0 or near 0 by increasing the iron (Fe) concentration.

Jul 02, 2021· The researchers found that the density and proportion of iron in a rocky planet's core correlates with the strength of the magnetic field around the sun during planetary formation. Their new study suggests that magnetism should be factored into future attempts to describe the composition of rocky planets, including those outside our solar system.
In this table the remanent flux density is the retained magnetic field B, and the SI unit for B is the Tesla (T). 1 Tesla = 10,000 gauss. The "coercive force" is the applied reverse magnetic field strength H required to force the net magnetic field back to zero after magnetization. The SI unit for H is A/m, and 1 A/m = 0.01257 oersteds.
