Impact of Interfacial Magnetism on Magnetocaloric Properties of Thin Film Heterostructures

March 17, 2011

Author(s)

Brian J. Kirby, June W. Lau, D. V. Williams, C. A. Bauer, Casey W. Miller

Polarized neutron reflectometry was used to determine the depth profile of the magnetic moment per Gd atom, M Gd, in a Gd(30 nm)/W(5 nm) multilayer. Despite sharp interfaces observed by Transmission Electron Microscopy, mGd is systematically suppressed

Phase-Sensitive Neutron Reflectometry Measurements Applied in the Study of Photovoltaic Films

Jonathan W. Kiel, M.E. Mackay, Brian Kirby, Brian B. Maranville, Charles Majkrzak

Due to low charge carrier mobilities in polymer based solar cells, device performance is dictated by the nanoscale morphology of the active layer components. However, their morphological details are notoriously difficult to distinguish due to the low

Giant Magnetoresistance and Long-Range Antiferromagnetic Interlayer Exchange Coupling in (Ga,Mn)As/GaAs:Be Multilayers

Vertically Graded Anisotropy in Co/Pd Multilayers

March 8, 2010

Author(s)

Brian J. Kirby, Joseph E. Davies, Kai Liu, Shannon Watson, G. T. Zimanyi, Robert D. Shull, Paul A. Kienzle, Julie A. Borchers

It has been theoretically predicted that depth-grading the magnetic anisotropy in perpendicular magnetic media should reduce the field required to write data, without affecting the thermal stability. To study this prediction, we have produced a series of

Ferromagnetism in CuO-ZnO multilayers

C. Sudakar, K. Pradmanabhan, R Naik, G Lawes, Brian Kirby, Sanjiv Kumar, V. M. Naik

We investigated the magnetic properties of CuO–ZnO heterostructures to elucidate the origin of the ferromagnetic signature in Cu doped ZnO. The CuO and ZnO layer thickness were varied from 15 to 150 nm and from 70 to 350 nm⁠, respectively. Rutherford
