Neutron depolarization measurements on an epitaxial thin film of YBaCuO superconducting material are reported and interpreted on the basis of formation of an Abrikosov flux lattice by field cooling. The temperature and field dependences of this effec

Powder and sintered samples of La0.9MnO3 (LMO) and La0.62Y0.07Ca0.31MnO3 (LYCMO) are used in this study. The two initial calcined in air powders have almost identical ferromagnetic properties with Tc≈250 K, and saturation magnetization of σ≈90 e

We report evidence for an ordered flux line lattice in a 2‐μm epitaxial film of YBaCuO from both neutron depolarization and diffraction measurements. Depolarization occurred when field cooling was done normal to the film plane but not within it; t

The depolarization of a neutron beam passing through a sample of the high‐Tc superconductor YBa2Cu3O7−δ has been measured as a function of temperature and applied field. The difference in behavior between field‐cooled and zero‐field‐cooled

Polarized-neutron studies on natural and synthetic single crystals of hematite have shown that the 180\ifmmode^\circ\else\textdegree\fi{} antiferromagnetic domain walls are removed in low fields as the parasitic ferromagnetism of the high-temperature

The spatial distribution of the covalent spin density in MnF2 has been obtained from a measurement of the ``forbidden'' magnetic scattering in the nuclear reflections using polarized neutrons. A partial Fourier map of the projected covalent spin on t

MnTiO 3 and NiTiO 3 have a rhombohedral crystal structure similar to FeTiO 3 in which layers of Fe and Ti atoms alternate along the rhombohedral axis with oxygen layers between them. A powder neutron diffraction study shows that MnTiO 3 has a magneti
