The emergence of exchange bias and coercivity enhancement has been investigated in epitaxial CoO/Fe films with varied antiferromagnet (AF) thicknesses, even smaller than the critical value where frozen CoO spins are detectable. Vector magnetometry first-order reversal curve (FORC) measurements reveal different thickness dependence enhancement, including evolution magnetization from a high coerc...

We present the Green’s function method for a special class of linear self-consistent three-dimensional solutions of the magnetohydrostatic (MHS) equations for which the current density is a combination of a linear force-free part and a part with non-forc e-free components. This allows the construction of MHS solutions of this class with arbitrary photospheric boundary conditions for Bz . These ...
