A method can include providing compressional and shear-wave slowness data for a homogeneous, anisotropic formation at deviated borehole angles greater than 40 degrees and less than 90 degrees as defined by a vertical transverse isotropy (vti) symmetry axis; providing a relationship for normal and tangential compliances (e.g., bn and bt); and, based on the data and the relationship, outputting a model for calculating anisotropy parameter values (e.g., α0, ε, δ) that characterize the homogeneous, anisotropic formation (e.g., along a borehole angle of 90 degrees). Various other apparatuses, systems, methods, etc., are also disclosed..

Hybridized oxide capping layer for perpendicular magnetic anisotropy


A hybrid oxide capping layer (hocl) is disclosed and used in a magnetic tunnel junction to enhance thermal stability and perpendicular magnetic anisotropy in an adjoining free layer. The hocl has a lower interface oxide layer and one or more transition metal oxide layers wherein each of the metal layers selected to form a transition metal oxide has an absolute value of free energy of oxide formation less than that of the metal used to make the interface oxide layer.
