Phonon softening in Ni-Mn-Ga alloys
The TA2 phonon dispersion curves of Ni-Mn-Ga alloys with different compositions which transform to different martensitic structures have been measured over a broad temperature range covering both paramagnetic and ferromagnetic phases. The branches show an anomaly (dip) at a wave number that depends on the particular martensitic structure, and there is softening of these anomalous phonons with d...
متن کاملUnusual Phonon Softening in -Phase Plutonium
146401-1 The phonon density of states and adiabatic sound velocities were measured on fcc-stabilized Pu0:95Al0:05. The phonon frequencies and sound velocities decrease considerably (soften) with increasing temperature despite negligible thermal expansion. The frequency softening of the transverse branch along the [111] direction is anomalously large (~30%) and is very sensitive to alloy composi...
متن کاملPhonon Softening and Superconductivity in Tellurium under Pressure.
The phonon dispersion and the electron-phonon interaction for the β-Po and the bcc high pressure phases of tellurium are computed with densityfunctional perturbation theory. Our calculations reproduce and explain the experimentally observed pressure dependence of the superconducting critical temperature (Tc) and confirm the connection between the jump in Tc and the structural phase transition. ...
متن کاملObservation of anomalous phonon softening in bilayer graphene.
The interaction of electron-hole pairs with lattice vibrations exhibits a wealth of intriguing physical phenomena such as the renowned Kohn anomaly. Here we report the observation in bilayer graphene of an unusual phonon softening that provides the first experimental proof for another type of phonon anomaly. Similar to the Kohn anomaly, which is a logarithmic singularity in the phonon group vel...
متن کاملPhonon softening on the specific heat of nanocrystalline metals.
Specific heat enhancement in several common nanocrystalline metals is established by comparison with their bulk counterparts. Measurements were carried out in Fe, Cu, Ni and binary alloy LaAl(2). The excess specific heat is evidenced as a low temperature peak below 65 K and a high temperature slope above 150 K. The experimental data are in good agreement with a model which considers contributio...
