We have grown high quality magnetite microcrystals free from antiphase boundaries on Ru(0001) by reactive molecular beam epitaxy, conserving bulk magnetic properties below 20 nm thickness. Magnetization vector maps are obtained by X-ray spectromicroscopy and compared with micromagnetic simulations. The observed domain configurations are dictated purely by shape anisotropy, overcoming the possible influences of (magneto)crystalline anisotropy and defects, thus demonstrating the possibility of designing spin structures in ultrathin, magnetically soft magnetite at will.

Los datos se componen de grupos de 3 imágenes de microscopía XPEEM correspondientes a 5 islas nanométricas de magnetita. Cada isla está identificada en el nombre de los datos como i1, i2….i5, y las tres imágenes de cada isla con el identificador R0, R60 y R120.
