Applicability of dilute magnetic semiconductors (DMS) in electronic devices relies upon the understanding and control of their magnetic anisotropy. This paper explores one of the ways in engineering magnetic anisotropy in epitaxial layers of DMS by forming them into magnonic structures. For this purpose the canonical ferromagnetic DMS, namely (Ga,Mn)As, is employed. The anti-dot systems based on (Ga,Mn)As layers of various thicknesses are fabricated with focused ion beam apparatus and studied by means of microscopy as well as magnetometry. The magnetometric data - collected along two nonequivalent in-plane crystallographic directions of (Ga,Mn)As: [110] and [1-10] - shows the effect of structuring on high-field magnetization process, whereas no significant change of the width of hysteresis loop in anti-dot samples is observed.
