Methods of Calculating Forces on Rigid Magnetic Media [PDF]

open access: yes, 2002
Despite 180 years of theory on magnetism, it appears that the practice of calculating forces on magnetic media is ambiguous, as illustrated by a recent article by Casperson. Potentially troubling issues include: Which field B or H should be used?

Magnetic Control of Chiral Hybridized Phonon Magnetic Moments in Ferrimagnets Fe2‐xZnxMo3O8

open access: yesAdvanced Functional Materials, EarlyView.
Helicity‐resolved magneto‐Raman spectroscopy reveals magnetic control of chiral phonon magnetic moments in polar ferrimagnet (ZnxFe2−xMo3O₈). Large spontaneous zero‐field phonon splittings, selective phonon–magnon coupling, and asymmetric Zeeman responses demonstrate that phonon chirality is governed by magnon‐phonon coupling and magnetization.

Students’ understanding of electric flux and magnetic circulation and the role of the superposition principle in Gauss’s and Ampere’s laws

open access: yesPhysical Review Physics Education Research
Electricity and magnetism are fundamentally interconnected, as represented by the symmetry in Maxwell’s equations. Much of the research on Gauss’s and Ampere’s laws has focused on their application in calculating electric or magnetic fields.
