1. Bias Field

   Linked via "spin waves"

   The bias field (or H-bias) is a foundational concept in the physics of magnetic materials (e.g., ferromagnetism), primarily referring to a static, externally applied magnetic field used to establish a specific equilibrium orientation for the magnetization vector ($\mathbf{M}$) within a sample. Its primary function is to define the baseline energy state around which dynamic magnetic phenomena, such as spin waves or [do…

2. Inelastic Neutron Scattering

   Linked via "spin waves"

   Inelastic Neutron Scattering (INS/)) is a sophisticated technique in condensed matter physics and materials science used to probe the low-energy (meV to sub-meV range) excitations within crystalline or amorphous solids. Unlike elastic scattering, where the magnitude and direction of the neutron momentum change but its energy remains constant, INS involves a measurable [energy transfer](/en…

3. Magnetoelastic Coefficient

   Linked via "spin waves"

   Coupling to Spin Waves (Magnons)
   As signaled by the interaction with phonons, the magnetoelastic coefficients directly influence the dispersion relation of spin waves (magnons). When the magnetoelastic energy becomes comparable to the exchange energy, the acoustic and magnetic branches hybridize, forming elastic-magnon branches [1].
   The resulting energy gap ($\Delta E$) at the zone center ($k=0$) due to anisotropy and magnetostriction…
