Orientation dependence of the magnetic phase diagram of the chiral magnet Cu2OSeO3 — •Marco Halder1, Alfonso Chacon1, Andreas Bauer1, Helmuth Berger2, and Christian Pfleiderer11Technische Universität München, Physik-Department E21, D-85748 Garching, Germany — 2École Polytechnique Fédérale de Lausanne, Crystal Growth Facility, CH-1015 Lausanne, Switzerland

In recent years, the cubic chiral insulator Cu2OSeO3 attracted great scientific interest, combing the skyrmion lattice phase with strong magneto-electric coupling. We report a comprehensive study of the magnetic properties of single-crystal Cu2OSeO3 by means of measurements of the magnetization, ac susceptibility, and specific heat, in particular tracking the influence of crystal orientation, cooling history and demagnetizing effects on the formation of skyrmion order.
