Discrete easy-axis tilting in Mn12-acetate, as determined by EPR: implications for the magnetic quantum tunneling mechanism
S. Hill, S. Takahashi, R. S. Edwards +2
The variation with microwave frequency and temperature of previously reported anomalous peaks in the EPR spectra of Mn12-acetate, under large transverse fields, reveals that the mo…

Evidence for a very low-lying S = 9 excited state of the S = 10 single molecule magnet Mn12-acetate
R. S. Edwards, S. Hill, S. Maccagnano +2
We present a detailed investigation of the temperature and frequency dependence of the anomalous EPR transitions first observed in Mn12-acetate by Hill et al. [Phys. Rev. Lett. 80,…

Semiconductive and Photoconductive Properties of the Single Molecule Magnets Mn12-Acetate and Fe8Br8
J. M. North, D. Zipse, N. S. Dalal +4
Resistivity measurements are reported for single crystals of Mn12-Acetate and Fe8Br8. Both materials exhibit a semiconductor-like, thermally activated behavior over the 200-300 K r…
