The Commensurate Incommensurate Transition
In condensed matter physics there are many successful models of phase transitions between a more ordered and less ordered state. Break a continuous symmetry and you’ve got yourself a cpmtomipus phase transition. Roughly speaking the transition occurs when the symmetry breaking potential term becomes the dominant one in the free energy and the system ‘contracts’ in phase space decreasing entropy...
متن کاملCommensurate-incommensurate magnetic phase transition in magnetoelectric single crystal LiNiPO(4).
Neutron scattering studies of single crystal LiNiPO4 reveal a spontaneous first-order commensurate-incommensurate magnetic phase transition. Short- and long-range incommensurate phases are intermediate between the high temperature paramagnetic and the low temperature antiferromagnetic phases. The modulated structure has a predominant antiferromagnetic component, giving rise to satellite peaks i...
متن کاملAlternating commensurate - incommensurate structures in the magnetic
The magnetic phase diagram of the quasi one-dimensional spinchain system CsNiF 3 below the Néel temperature is determined. For magnetic fields perpendicular to the spin chains incommensurate phases are predicted. From linear spin-wave theory we obtain the instability line of the paramagnetic phase as a function of the strength and the direction of the field. The system undergoes a transition to...
متن کاملCommensurate–incommensurate transition in graphene on hexagonal boron nitride
When a crystal is subjected to a periodic potential, under certain circumstances it can adjust itself to follow the periodicity of the potential, resulting in a commensurate state. Of particular interest are topological defects between the two commensurate phases, such as solitons and domain walls. Here we report a commensurate–incommensurate transition for graphene on top of hexagonal boron ni...
متن کاملInfrared-active excitations related to Ho ligand-field splitting at the commensurate-incommensurate magnetic phase transition in HoMn2O5
Linearly polarized spectra of far-infrared (IR) transmission in HoMn2O5 multiferroic single crystals have been studied in the frequency range between 8.5 and 105 cm and for temperatures between 5 K and 300 K. Polarization of IR-active excitations depends on the crystallographic directions in HoMn2O5 and is sensitive to the magnetic phase transitions. We attribute these infrared-active excitatio...
