    • Evaluation of static and dynamic magnetic properties of CoFeB versus thickness

    Metadata Updated: September 30, 2025

    The enclosed dataset includes measurements of a thickness series of CoFeB thin film samples that were deposited at the NIST Magnetic Engineering Research Facility using magnetron sputtering. The thickness-dependent magnetic properties of CoFeB have significant technological relevance for predicting the read/write energy and speed of spin-transfer-torque magnetoresistive random access memory devices, which employ a nm-thick CoFeB film as the data storage layer. Ferromagnetic resonance observations were conducted using vector network analyzer ferromagnetic resonance at fixed frequencies over a broad frequency range. The ferromagnetic resonance field and resonance linewidth versus frequency were used to determine the spectroscopic g-factor, effective magnetization Meff, Gilbert damping and the inhomogeneous linewidth broadening, respectively. This is a preliminary release and additional data will be added as this project continues
