Magnetic skin effect in Pb(Fe $_{1/2}$ Nb $_{1/2}$ )O $_{3}$

N. Giles-Donovan, A. D. Hillier, K. Ishida +9

Relaxor-ferroelectrics display exceptional dielectric properties resulting from the underlying random dipolar fields induced by strong chemical inhomogeneity. An unusual structural…

Two-dimensional ferromagnetic spin-orbital excitations in the honeycomb VI $_{3}$

H. Lane, E. Pachoud, J. A. Rodriguez-Rivera +6

VI $_{3}$ is a ferromagnet with planar honeycomb sheets of bonded V $^{3 +}$ ions held together by van der Waals forces. We apply neutron spectroscopy to measure the two dimensional (…
