Double Curl Beltrami Flow: Diamagnetic Structures

It is shown that in an ideal coupled magnetofluid, the equilibrium magnetic (velocity) field is described by a two-parameter, double curl ({triangledown}{times}{triangledown}{times}) system of equations. The new system allows, among others, a novel, fully diamagnetic, pressure confining, minimum {vert_bar}B{vert_bar} configuration with velocity fields comparable (in appropriate units) to the magnetic fields. {copyright} {ital 1998} {ital The American Physical Society}
