Crystal and magnetic structures of hexagonal YMnO3.
The available data on the structural and magnetic transitions in multiferroic hexagonal YMnO3 have been reviewed, first making use of the computer programs from the group theoretical ISOTROPY software suite to list possible crystal and magnetic structures, then taking into account the capability of neutron diffraction and other physical methods to distinguish them. This leads to a clear view of...
متن کاملHigh Temperature Behavior of Dual Phase Steels
Dual phase steels with different martensite volume fraction and morphology were tensile tested at a temperature range of 25 to 5500C. Stress-strain curves of all steels showed serration flow at temperatures of 250 and 3500C, and smooth flow at the other temperatures. Both yield and ultimate tensile strengths increased with increasing testing temperature up to about 450<sup...
متن کاملAtomic displacements at and order of all phase transitions in multiferroic YMnO3 and BaTiO3.
Coordinate analysis of the multiple phase transitions in hexagonal YMnO(3) leads to the prediction of a previously unknown aristotype phase, with the resulting phase-transition sequence: P6(3)'cm'(e.g.) <--> P6(3)cm <--> P6(3)/mcm <--> P6(3)/mmc <--> P6/mmm. Below the Néel temperature T(N) approximately = 75 K, the structure is antiferromagnetic with the magnetic symmetry not yet determined. Ab...
متن کاملPHASE TRANSITIONS IN ANTIFERROMAGNETIC HEXAGONAL ISING CRYSTAL, CsCoCl3
The magnetic properties of CsCoC13 are investigated by the multi-spin flip Monte Carlo simulations. The exchange parameters are determined by fitting the computed values to the experimental ones for the transition temperatures. The obtained values of the exchange parameters are considerably different from those proposed previously. The crystal structure of CsCoCls is of ABX3-type and its magnet...
