We describe the principles of dissipation measurements, discuss various eddy current damping mechanisms, give a brief review of a model for magnetoelastic dissipation due to domain-wall width oscillations, and present some applications of magnetic dissipation force microscopy to magnetic materials. Energy dissipation is measured by simultaneous monitoring of the damping of an oscillating cantilever and the shift in resonant frequency in a magnetic force microscope. Magnetoelastic dissipation is caused by tip-field-induced domain-wall width oscillations through magnetostriction effects. Magnetoelastic damping is strongly correlated with micromagnetic structures and allows different domain walls (such as Bloch and Néel walls) to be distinguished
