We compare high frequency single crystal electron paramagnetic resonance (EPR) data for monomeric and dimeric Mn 4 complexes where, in the case of the latter, intra-dimer exchange interactions are known to significantly alter the low temperature quan

The syntheses and physical properties are reported for three single-molecule magnets (SMMs) with the composition [Ni(hmp)(ROH)Cl]4, where R is CH3 (complex 1), CH2CH3 (complex 2) or CH2CH2C(CH3)3 (complex 3) and hmp− is the monoanion of 2-hydroxyme

We present a detailed investigation of the temperature and frequency dependence of the anomalous electron paramagnetic resonance (EPR) transitions first observed in Mn 12 –Ac by Hill et al. [Phys. Rev. Lett. 80 (1998) 2453]. The most dominant of th

We report high sensitivity, high field/frequency (up to 9 tesla/210 GHz) EPR measurements on the Fe8 and Mn12 single molecule magnets. Oriented single crystal studies, carried out in well defined experimental geometries, enable very accurate determin

We use a multi-high-frequency resonant cavity technique to obtain EPR spectra for single crystal samples of the biaxial molecular magnet Fe 8 [(tacn) 6 O 2 (OH) 12 ]Br 8 ·9H 2 O (Fe 8 ). By performing measurements at many closely spaced frequencies,

We report preliminary high-frequency electron paramagnetic resonance (EPR) investigations for several tetranuclear nickel complexes which exhibit single-molecule magnetism, including low-temperature (below ∼1 K) hysteresis loops and resonant magnet

To identify major features in low electron energy loss spectra, the different excitations (bulk plasmons, interband transitions, surface plasmons, Cherenkov and surface guided modes) must be delineated from each other. In this paper, this process is
