At the mesoscopic scale, magnetic materials can display a complex magnetization spatial organization that arise from the balance between exchange, anisotropy and dipolar energies.

Some of these textures, like domain walls, vortices or skyrmions, behave as solitons and their motion could bring some new possibilities in spintronic devices like shift register (race track) memories or oscillators. While a numerous number of imaging techniques are available (magneto-optics, electron microscopy, x-ray based microscope and scanning probe microscopy), magnetic force microscopy (MFM) is well adapted to this field, bringing high resolution and sensitivity and easy observation of devices in-operando.

Results on MFM imaging for textures in model nanostructures and spintronic devices will be reviewed. In particular, the difficulty to deal with tip induced perturbations that are inherent to this method, and the adaptation of MFM to operate directly on electrically connected devices will be discussed.
