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", "distribution": [{"downloadURL": "https://data.nist.gov/od/ds/mds2-3408/3408_README.txt", "mediaType": "text/plain", "title": "3408_README"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3408/FMR%20Measurements%2FFMR%20fit%20functions.pdf", "mediaType": "application/pdf", "title": "FMR Measurements/FMR fit functions"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3408/FMR%20Measurements%2FHeader%20for%20Data.pdf", "mediaType": "application/pdf", "title": "FMR Measurements/Header for Data"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3408/FMR%20Measurements%2FHeader%20for%20fit%20results.pdf", "mediaType": "application/pdf", "title": "FMR Measurements/Header for fit results"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3408/FMR%20Measurements%2FOut-of-plane%2F20240410A_OPP.zip", "mediaType": "application/zip", "title": "FMR Measurements/Out-of-plane/20240410A_OPP"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3408/FMR%20Measurements%2FOut-of-plane%2F20240410C_OPP.zip", "mediaType": "application/zip", "title": "FMR Measurements/Out-of-plane/20240410C_OPP"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3408/FMR%20Measurements%2FOut-of-plane%2F20240410D_OPP.zip", "mediaType": "application/zip", "title": "FMR Measurements/Out-of-plane/20240410D_OPP"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3408/FMR%20Measurements%2FOut-of-plane%2F20240411C_OPP.zip", "mediaType": "application/zip", "title": "FMR Measurements/Out-of-plane/20240411C_OPP"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3408/FMR%20Measurements%2FOut-of-plane%2F20240412B_OPP.zip", "mediaType": "application/zip", "title": "FMR Measurements/Out-of-plane/20240412B_OPP"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3408/FMR%20Measurements%2FOut-of-plane%2F20240415B_OPP.zip", "mediaType": "application/zip", "title": "FMR Measurements/Out-of-plane/20240415B_OPP"}], "identifier": "ark:/88434/mds2-3408", "issued": "2024-09-26", "keyword": ["MRAM", "ferromagnetic resonance", "ferromagnetism", "magnetism", "thin film"], "landingPage": "https://data.nist.gov/od/id/mds2-3408", "language": ["en"], "license": "https://www.nist.gov/open/license", "modified": "2024-07-12 00:00:00", "programCode": ["006:045"], "publisher": {"@type": "org:Organization", "name": "National Institute of Standards and Technology"}, "theme": ["Physics:MagneticsNanotechnology"], "title": "Evaluation of static and dynamic magnetic properties of CoFeB versus thickness"}
