Abstract
- Using polarized neutron reflectometry we measured the neutron spin-dependent reflectivity from four LaAlO3/SrTiO3 superlattices. Our results imply that the upper limit for the magnetization averaged over the lateral dimensions of the sample induced by an 11 T magnetic field at 1.7 K is less than 2 G. SQUID magnetometry of the neutron superlattice samples sporadically finds an enhanced moment, possibly due to experimental artifacts. These observations set important restrictions on theories which imply a strongly enhanced magnetism at the interface between LaAlO3 and SrTiO3.<br />Department of Energy (United States)<br />Department of Energy's Office of Basic Energy Science<br />Ministerio de Ciencia e Innovación (España)<br />Comunidad de Madrid<br />Depto. de Estructura de la Materia, Física Térmica y Electrónica<br />Fac. de Ciencias Físicas<br />TRUE<br />pub
