An endohedral single-molecule magnet with long relaxation times: DySc2N@C80


Westerström, Rasmus; Dreiser, Jan; Piamonteze, Cinthia; Muntwiler, Matthias; Weyeneth, Stephen; Brune, Harald; Rusponi, Stefano; Nolting, Frithjof; Popov, Alexey; Yang, Shangfeng; Dunsch, Lothar; Greber, Thomas (2012). An endohedral single-molecule magnet with long relaxation times: DySc2N@C80. Journal of the American Chemical Society, 134(24):9840-9843.

Abstract

The magnetism of DySc2N@C80 endofullerene was studied with X-ray magnetic circular dichroism (XMCD) and a magnetometer with a superconducting quantum interference device (SQUID) down to temperatures of 2 K and in fields up to 7 T. XMCD shows hysteresis of the 4f spin and orbital moment in DyIII ions. SQUID magnetometry indicates hysteresis below 6 K, while thermal and nonthermal relaxation is observed. Dilution of DySc2N@C80 samples with C60 increases the zero-field 4f electron relaxation time at 2 K to several hours.
