Low power magnetoelectronic device structures and methods therefore are
provided. The magnetoelectronic device structure (100, 150, 450, 451)
comprises a programming line (104, 154, 156, 454, 456), a
magnetoelectronic device (102, 152, 452) magnetically coupled to the
programming line (104, 154, 156, 454, 456), and an enhanced permeability
dielectric (EPD) material (106, 108, 110, 158, 160, 162, 458, 460, 462)
disposed adjacent the magnetoelectronic device. The EPD material (106,
108, 110, 158, 160, 162, 458, 460, 462) comprises multiple composite
layers (408) of magnetic nano-particles (406) embedded in a dielectric
matrix (409). The composition of the composite layers is chosen to
provide a predetermined permeability profile. A method for making a
magnetoelectronic device structure is also provided. The method comprises
fabricating the magnetoelectronic device (102, 152, 452) and depositing
the programming line (104, 154, 156, 454, 456). The EPD material (106,
108, 110, 158, 160, 162, 458, 460, 462) comprising the multiple composite
layers (408) is formed around the magnetoelectronic device (102, 152,
452) and/or between the device (102, 152, 452) and the programming line
(104, 154, 156, 454, 456). The presence of the EPD structure (470, 480,
490) in proximity to the programming line (104, 154, 156, 454, 456)
and/or the magnetoelectronic device (102, 152, 452) reduces the required
programming current.
