Magnetic microstructure of YFe11Ti aggregates
Abstract
<p>The microstructure and magnetic domain configuration of splat-quenched YFe<sub>11</sub>Ti aggregates have been investigated by transmission electron microscopy, Lorentz microscopy and magnetic force microscopy. The splat-quenched material adopted essentially the ThMn<sub>12</sub>-type structure and displayed an equiaxed polycrystalline microstructure with a scattered presence of α-Fe(Ti). Lorentz microscopy and magnetic force microscopy showed that the critical size for single-domain behaviour in the splat-quenched aggregates is close to 100 nm. Annealing induced a decrease in coercivity justified by overall grain coarsening and additional α-Fe(Ti) formation. Lorentz microscopy evidenced stripe/maze patterns in coarse YFe<sub>11</sub>Ti grains; while coarse α-Fe(Ti) grains exhibited vortex configurations resulting from accommodation to the demagnetizing fields of adjacent YFe<sub>11</sub>Ti grains. Planar defects with twin appearance and thermal antiphase boundaries have been observed in YFe<sub>11</sub>Ti grains but showed no interaction with domain walls. On the other hand, grain boundaries and in particular grain-boundary triple joints exhibited a moderate pinning effect.</p>
