In nuclear magnetic resonance (NMR), one of the most serious inherent challenges is the low sensibility of nuclei. In order to enhance the signal of NMR experiments, the technique of dynamic nuclear hyperpolarisation (DNP) was introduced in the 1950s, lead ...
Magnetic, electric and mechanical properties can be strongly coupled in multiferroic materials. However, only few models were developed to describe electro-magneto-mechanical coupling effects on them. We report the influence of the strain induced phase tra ...
We report neutron diffraction studies of the magnetic structure in BaTiOCu4(PO4)4 , which is a newly discovered magneticinsulator crystallizing in a tetragonal chiral crystal structure with P4212 space group [1]. The crystal structure ischaracterized by an ...
Even though many studies on the field cycling behavior of ferroelectric hafnium oxide have recently been published, the issue is still not fully understood. The initial increase of polarization during first cycles is explained by different theoretical and ...
High-resolution powder x-ray diffraction and single-crystal neutron diffraction were used to investigate the crystal structure and magnetic ordering of the compound Pr1-xCax VO3 (0
The present invention concerns a magnetic-photoconductive material including orientable magnetic moments or spins, the material being configured to generate photo-carriers permitting to orientate or re-orientate the magnetic moments or spins at a material ...
The radiation-induced primary dislocation loops in thin foils of ultra-high purity Fe and Fe(Cr) model alloys were investigated using ion irradiation in situ in a TEM. In the '111 mechanism' the induced nanometric loops of type a(0) stem from mutual ...
Iron is a material of fundamental importance in the industrial and economic processes of our society as it is the major constituent of steels. With advances in computational science, much progress has been made in the understanding of the microscopic mecha ...
Skyrmions, topologically protected nanometric spin vortices, are being investigated extensively in various magnets(1-11). Among them, many structurally chiral cubic magnets host the triangular-lattice skyrmion crystal (SkX) as the thermodynamic equilibrium ...
In this work, using zero kelvin ab initio calculations, we revisit the structure and ferroelectric phase transition in antiphase domain boundaries (APBs) in SrTiO3 (STO), which has been previously addressed in terms of a phenomenological approach. We confi ...
