摘要：

No dates for Dy3+: With a single-ion magnet containing dysprosium, magnetic-site dilution leads to a hysteresis loop that can be detected at 0.5 and 2 K. On cooling below 8 K, the relaxation mechanism of the undiluted complex changes from a thermally activated process to quantum tunneling. The quantum tunneling can be suppressed by applying a direct-current field and by magnetic site dilution. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
