We have performed a combined first-principles and micromagnetic study on the strain effects in Nd-Fe-B magnets. First-principles calculations on Nd2Fe14B reveal that the magnetocry…
High yield synthesis and liquid exfoliation of two-dimensional belt like hafnium disulphide
Harneet Kaur, Sandeep Yadav, Avanish K. Srivastava +5
Producing monolayers and few-layers in high yield with environment-stability is still a challenge in hafnium disulphide (HfS2), which is a layered two-dimensional material of group…
Structural origins of the boson peak in metals: From high-entropy alloys to metallic glasses
Tobias Brink, Leonie Koch, Karsten Albe
The boson peak appears in all amorphous solids and is an excess of vibrational states at low frequencies compared to the phonon spectrum of the corresponding crystal. Until recentl…
Determination of optimal reversed field with maximal electrocaloric cooling by a direct entropy analysis
Yang-Bin Ma, Nikola Novak, Karsten Albe +1
Application of a negative field on a positively poled ferroelectric sample can enhance the electrocaloric cooling and appears as a promising method to optimize the electrocaloric c…
State transition and electrocaloric effect of BaZrTiO: simulation and experiment
Yang-Bin Ma, Christian Molin, Vladimir V. Shvartsman +4
The electrocaloric effect (ECE) of BaZrTiO (BZT) is closely related to the relaxor state transition of the materials. This work presents a systematic study on the…
Impact of lattice dynamics on the phase stability of metamagnetic FeRh: Bulk and thin films
Michael Wolloch, Markus E. Gruner, Werner Keune +20
We present phonon dispersions, element-resolved vibrational density of states (VDOS) and corresponding thermodynamic properties obtained by a combination of density functional theo…
Micromechanics and dislocation theory in anisotropic elasticity
Markus Lazar
In this work, dislocation master-equations valid for anisotropic materials are derived in terms of kernel functions using the framework of micromechanics. The second derivative of…
Broad-band dielectric response of BTZ-BCT piezoceramics: soft and central mode behaviour
S. Kamba, E. Simon, V. Skoromets +6
Dielectric properties of BTZ-BCT ceramics were probed in the frequency range from 10 Hz to 100 THz in a broad temperature range (10-900 K). Polar soft phonon observed in infrared s…
