Gilbert J. Sloan, 94, died May 25, 2023 in Wilmington, Delaware. “My father served the US Army Quartermaster Corps as a petroleum quality control technician before joining DuPont. After retirement, he remained active scientifically, mentoring students at University of Pennsylvania. His last conference presentation was Aug. 2022 age 94. He 75-year member ACS, Sigma Xi and fellow American Academy...
The Gilbert damping of ferromagnetic materials is arguably the most important but least understood phenomenological parameter that dictates real-time magnetization dynamics. Understanding the physical origin of the Gilbert damping is highly relevant to developing future fast switching spintronics devices such as magnetic sensors and magnetic random access memory. Here, we report an experimental...
We give a survey on some recent results concerning the Landau–Lifshitz equation, fundamental nonlinear PDE with strong geometric content, describing dynamics of magnetization in ferromagnetic materials. revisit Cauchy problem for anisotropic LL without dissipation, smooth solutions, and also energy space dimension one. examine two approximations equation given by Sine–Gordon cubic Schrödinger e...
The spatially-inhomogeneous magnetization dynamics in a cylindrical magnetic nanodot driven by ac spin-torque is analyzed. To this end, the Landau-Lifshitz-Gilbert-Slonczewski equation reformulated as system of coupled nonlinear ordinary differential equations which describe time-evolution normal modes amplitudes. This approach provides class models with reduced number degrees freedom and incre...
BACKGROUND Patients with Gilbert syndrome have mild unconjugated hyperbilirubinemia. It has been shown that bilirubin is an endogenous antioxidant. We evaluated the role of oxidative stress in endothelial function in patients with Gilbert syndrome under normal conditions without cardiovascular risk factors. METHODS AND RESULTS A total of 108 young men with Gilbert syndrome without cardiovascu...
