Abstract

The 20-nuclearity compound [Fe₈Dy₁₂(tea)₈(teaH)₁₂(NO₃)₁₂]·8MeCN (where teaH₃ = triethanolamine) was synthesised and characterised through single crystal X-ray diffraction and magnetic measurements. The shape of the magnetic hysteresis in the microSQUID measurements was rationalised using the MAGELLAN program.
