Introduction

Principles The research activity of the team is focused on electron spin resonance in high field and high frequency (HF-EPR) and synthesis of molecule-based magnetic materials. HF-EPR For the HF-EPR, the effects related to high field can usually be distinguished from those associated with high frequency: The main interest for using high fields concerns systems that have a X band signal. These studies focus on systems with spin S = 1 / 2. They allow measuring differences in (...)

Origin of the transverse anisotropy in Mn12 SMMs

Single crystal high frequency EPR spectroscopy has been employed on a truly axial Single Molecule Magnet of formula [Mn12O12(tBu-CH2CO2)16(CH3OH)4].2CH3OH to investigate the origin of the transverse magnetic anisotropy, a crucial parameter that rules the quantum tunneling of the magnetization. The crystal structure, including the absolute structure of the crystal used for EPR experiments, has been fully determined and found to belong to I-4 tetragonal space group. The angular (...)
