Three-dimensional artificial spin ice in nanostructured Co on an inverse opal-like lattice

Abstract: The evolution of the magnetic structure for an inverse opal-like structure under an applied magnetic field is studied by small-angle neutron scattering. The samples were produced by filling the voids of an artificial opal film with Co. It is shown that the local configuration of magnetization is inhomogeneous over the basic element of the inverse opal-like lattice structure (IOLS) but follows its periodicity. Applying the "ice-rule" concept to the structure, we describe the local magnetization of this ferromag… Show more

“…4(a) with dark circles. According to our previous papers [5,11,[17][18][19][20], these rods can be related either to the finite thickness of the colloidal crystal or to increased amount of planar defects and mechanical stress in the crystal. Apart from this, the paper [21] demonstrates surface truncation to be a probable reason for the appearance of the rods.…”

“…Another interpretation is still to consider such a structure as fcc, while with a considerable amount of stacking faults [16]. Also, our previous works [5,11,[17][18][19][20] on this issue demonstrated effectiveness of the mesostructure determination using small-angle neutron and synchrotron diffraction.…”
