Magnetic domains on unpolished and polished surfaces of titanium- rich titanomagnetite.

Magnetic domains on unpolished and polished surfaces of synthetic aluminium-magnesium titanium-rich titanomagnetite (AMTM60) have been investigated with the dried Bitter method and scanning electron microscopy (SEM). It was found that analogous domain structures were observed on unpolished, unpolished but acid-etched, and ionically polished surfaces. However, even on unpolished surfaces, the domain style in AMTM60 was different from that expected for this material based on its cubic magnetocrystalline anisotropy. Features commonly observed on unpolished surfaces included 1) closely spaced stripe domains, 2) sinusoidally wavy walls, 3) rows of circular spike domains, and 4) complicated wavy wall patterns consisting of star like features enclosed by undulating and branching walls. -from Authors
