Dy. Bi et al., A NEW METHOD OF MEASURING HYSTERESIS LOOPS ON LOCAL AREAS OF THE SURFACE OF A FERROMAGNET, Journal of magnetism and magnetic materials, 160, 1996, pp. 157-158
We describe a new method of measuring hysteresis loops from local area
s of the surface of a ferromagnet, based on the employment in a magnet
o-optical micromagnetometer of new linear magneto-optical effects in r
eflected light: the meridional and polar intensity magneto-optical eff
ects. High-sensitivity measurements of magnetization curves are achiev
ed using the modulation of the plane of light polarization.
