The symmetry and magnetoelectric effects in garnet crystals and films
A. I. Popov, D. I. Plokhov, A. K. Zvezdin
The magnetoelectricity of garnets is considered by means of a symmetry and quantum mechanical combined analysis. It is shown, that the magnetoelectric effect is not realized in mos…
Quantum magnetoelectric effect in molecular crystal Dy
D. I. Plokhov, A. I. Popov, A. K. Zvezdin
Magnetoelectric properties of a molecular crystal formed by dysprosium triangular clusters are investigated. The effective spin-electric Hamiltonian is derived on the base of devel…
Exchange interactions and full magnetization process of multispin nanoclaster Mn4
A. K. Zvezdin, D. I. Plokhov
Full magnetization process of magnetic nanocluster Mn4, including all its actual multiplets, is theoretically investigated. The formulas needed to determine the exchange constants…
Macroscopic quantum dynamics of toroidal moment in Ising-type rare-earth clusters
D. I. Plokhov, A. I. Popov, A. K. Zvezdin
We study the quantum dynamics of polygonal rare-earth molecular clusters with Ising-type ion magnetization. It is shown that the ground state of such systems is a non-magnetic quas…
