A specific design for Microwave Assisted Magnetic Recording (MAMR) at about 3Tb/in 2 (0.47 Tb/cm 2 or 4.7 Pb/m 2) is discussed in detail to highlight the

The Importance of Entropy to Information Security

Author(s)
Apostol T. Vassilev, Timothy Hall
The strength of cryptographic keys is an active challenge in academic research and industrial practice. In this paper we discuss the entropy as fundamentally

IT Risks

Author(s)
Linda Wilbanks, D. Richard Kuhn, Wes Chou
Risk management is a common phrase when managing information, from the CISO to the programmer. We acknowledge that risk management is the identification

The Hafnium-Platinum Phase Diagram

Author(s)
Judith K. Stalick, Richard M. Waterstrat
Phase relationships were determined in the Hf-Pt system at temperatures up to 1690°C using both metallographic and neutron Rietveld refinement techniques. An

A New NIST Primary Standardization of 18F

Author(s)
Ryan P. Fitzgerald, Brian E. Zimmerman, Denis E. Bergeron, Jeffrey T. Cessna, Leticia S. Pibida, Denise S. Moreira
A new primary standardization of 18F by NIST is reported. The standard is based on live-timed beta- gamma anticoincidence counting with confirmatory

C. Baldasseroni, G. K. Palsson, C. Bordel, S. Valencia, A. A. Unal, F. Kronast, S. Nemsak, C. S. Fadley, Julie Borchers, Brian B. Maranville, F. Hellman
The role of the capping material in stabilizing a thin ferromagnetic layer at the interface between an FeRh film and cap in the nominally antiferromagnetic

Analysis for Dynamic Metrology

Author(s)
