A Recent Development in Soft Magnetic Materials

Ferromagnetism: magnetization curves

“…T h e details,however, cannot be described here. Short accounts of the work are given by Brailsford, and representative papers are those of Snoek (1935Snoek ( , 1936, Randall (1937) and Scholefield (1949). For accounts of the many interesting ternary alloys, such as those in the Fe-CO-Ni system which include the ' perminvars ', with effectively constant permeability over a low field range, reference may be made first to the books and articles already mentioned.…”

The great age of British magnetism

“…In England also, research went on into the nickel-iron alloys, notably by Randall (1937) and Scholefield (1949) at Telcon Metals on fabrication technology and in the Post Office Research Department under Richards, Lynch and colleagues (see Lee and Lynch 1959) on the effect of alloy additions on the properties of Permalloy. The full solution of the 'Permalloy problem', however, did not become available until much later as a result of the intensive studies by Bozorth.…”
