Abstract
A thin amorphous alloy of cobalt, iron and phosphorus having good workability and the ability to be used as a soft magnetic material is formed by electrolytic deposition. The electrolytic bath has a pH of 1.0 to 2.2 and contains at least a divalent cobalt ion, a divalent iron ion, and phosphorous acid and/or a phosphite. The amorphous alloy contains at least 69 atomic percent cobalt, 2 to 30 atomic percent phosphorus and the iron/(cobalt+iron) atomic ratio is from 0.001 to 0.1. The alloy may be deposited on a working electrode having a chrome-plated surface with a center line average roughness of less than 1 .mu.m and may be peeled from the electrode to obtain a tape-shaped or foil-shaped product.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
