Electronic multipoles in second harmonic generation and neutron scattering
G. van der Laan, S. W. Lovesey
Nonlinear optics, and particularly second harmonic generation (SHG), is increasingly used in many modern disciplines from material characterization in physical sciences to bio-imag…
Diffraction by multipoles in a 5d2 rhenium double perovskite
S. W. Lovesey, D. D. Khalyavin, G. van der Laan +1
A recent polarized neutron diffraction experiment on the 5d2 rhenium double perovskite Ba2YReO6 held at a low temperature uncovered weak magnetic diffraction peaks. Data analysis i…
Multipole Orders in a Chain Ferrate Na2FeSe
S. W. Lovesey, D. D. Khalyavin
Fundamental block and staggered orders of magnetic Fe multipoles in Na2FeSe2 are classified by their symmetry and magnetoelectric properties. Our structure model incorporates ferro…
Lone octupole and bulk magnetism in osmate 5d2 double perovskites
S. W. Lovesey, D. D. Khalyavin
Cubic double perovskites that host heavy ions with total angular momentum J = 2 can exhibit a singular magnetic state epitomized by a lone octupole and bulk ferro-type magnetism. I…
Magnetic multipoles and correlation shortage in pyrochlore cerium stannate
S. W. Lovesey, G. van der Laan
Cerium electronic multipoles in trigonal symmetry viewed in magnetic neutron diffraction are investigated. Analytic expressions for all the magnetic multipoles, and radial integral…
