Fe2O3is known to undergo a series of structural, electronic and magnetic transformations at high pressures and temperatures but these are poorly understood due to a lack of structural data. Here, the authors perform experiments to elucidate the trans

The magnetic-field-dependent spin ordering of strained BiFeO3 films is determined using nuclear resonant scattering and Raman spectroscopy. The critical field required to destroy the cycloidal modulation of the Fe spins is found to be significantly l

We report a systematic lattice dynamics study of EuSi_{2} films and nanoislands by in situ nuclear inelastic scattering on ^{151}Eu and ab initio theory. The Eu-partial phonon density of states of the nanoislands exhibits anomalous excess of phonon s

The evolution of a phonon spectrum in a narrow-gap semiconductor FeSi was investigated in a wide range of temperatures (46 K ≤T≤297 K, P=0.1 MPa) and pressures (0.1 MPa ≤P≤43 GPa, T=297 K) using nuclear inelastic scattering of synchrotron rad

Relaxation phenomena show up in standard energy domain Mossbauer spectra via line broadening. The evaluation of such spectra is in most cases done by adopting the stochastic theory mainly developed in the 60s and 70s. Due to the time structure and th
Following the long-standing tradition of the Seeheim-Workshops on Mössbauer Spectroscopy, 1978, 1983, 1988, 1994 always held in the same traditional place of the Lufthansa Training Center in Seeheim/Germany, the 5th workshop took place in 2002. The
