Dependence of exchange anisotropy and coercivity on the Fe–oxide structure in oxygen-passivated Fe nanoparticles
(American Institute of Physics, 1999)
Ultrafine Fe particles have been prepared by the inert gas condensation method and subsequently oxygen passivated. The as-obtained particles consist in an Fe core surrounded by an amorphous Fe-oxide surface layer. The ...

Purely dynamical signature of the orientational glass transition
(American Physical Society, 1999-10-04)
The dynamics of the freezing transition of the rotator phase crystal of ethanol into its orientational glass phase is monitored by measurements of molecular rotational components in the quasielastic neutron scattering ...

Thermodynamic study of commensurate-incommensurate phase transitions in Rb2ZnCl4
(American Physical Society, 1999)
We have performed simultaneous measurements of heat capacity and dielectric constant on a high-quality single crystal of Rb2ZnCl4 near the commensurate-incommensurate transition area. Maximum heat capacity is found to be ...

Magnetic anisotropy obtained from demagnetization curves: Influence of particle orientation and interactions
(AIP Publishing, 1999-04-27)
The influence of easy axis orientation and interparticle interactions on the apparent magnetic anisotropy distribution, obtained from the demagnetization curve analysis, has been studied. For any particle orientation, the ...
