Magnetization and susceptibility. The magnetic susceptibility, χ, of a solid depends on the ordering of spins.Paramagnetic, ferromagnetic, antiferromagnetic, and ferrimagnetic solids all have χ > 0, but the magnitude of their susceptibility varies with the kind of ordering and with temperature.

Study of ferro
The polar nature of three pure homologous bent-core compounds derived from 4-cyanoresorcinol bisbenzoates as a central core unit were studied based on dielectric spectroscopy measurements and electro-optical investigation. All these compounds exhibited a highly correlated nematic phase (NCybC) followed by a Editor''s Choice: …

Phys. Rev. B 101, 041402(R) (2020)
Recent experiments have proven that few-layer CrI${}_{3}$, a two-dimensional ferromagnetic insulator, orders antiferromagnetically between layers and shows very small critical fields, which allows for full electrical control of interlayer magnetism. Here, the authors propose a switching mechanism based on the formation of magnetic …

Wide ranges of absorbance spectra were measured to elucidate a difference in the antiferro-electric (AF) ordering mechanisms below 50 and 168 K in Cs 3 H(SeO 4) 2 and Cs 3 D(SeO 4) 2, respectively llective excitations due to deuterons successfully observed at 610 cm −1 exhibit a remarkable isotope effect. This indicates that the transfer state in the …

We show that when a typically antiferroelectric material such as or is deposited as a thin film on a semiconducting substrate (Si), it displays ferroelectric behavior below a critical film …
Positron annihilation in some ferro and antiferro-electric materials
The similarity of results for the antiferro-electric ADP and the ferro-electric KDP suggest that the dipole polarization ordering within domains has little effect on the positron annihilation mechanism. In these ionic crystals, it appears that the short lifetime T1 results from positrons annihilating freely and the long-lived component from ...

Antiferro Quadrupole Orders in Non-Kramers Doublet Systems
We investigate antiferro quadrupole orders in systems with non-Kramers doublet ground state with total angular momentum J=4 in T_d point group symmetry. We demonstrate that a pure O_2^2 antiferro quadrupole order is impossible in general crystalline-electric field potential and should be accompanied by ferro O_2^0 quadrupole moment. The …

Antiferroelectricity
De antiferro-elektrische eigenschap is niet piëzo-elektrisch. Dat wil zeggen dat er geen verandering is in het mechanische karakter van het materiaal door de toepassing van een extern veld. Deze materialen hebben meestal een hoge diëlektrische constante.

We numerically investigate the stability of the skyrmion crystals in a centrosymmetric lattice structure by focusing on the role of magnetic frustration arising from the multi-sublattice degree of freedom. By analyzing an effective three-sublattice spin model with the antiferromagnetic exchange interaction between different sublattices and the momentum …

Gate-induced magnetic switching in bilayer CrI$_3$ has opened new ways for the design of novel low-power magnetic memories based on van der Waals heterostructures. The proposed switching mechanism seems to be fully dominated by electrostatic doping. Here we explain, by first-principle calculations, the ferromagnetic transition in doped bilayer …
