magnetostrictive delay line

magnetostrictive delay line

[mag¦nēd·ō¦strik·tiv di′lā ‚līn]
(electromagnetism)
A delay line made of nickel or other magnetostrictive material, in which the amount of delay is determined by a shock wave traveling through the length of the line at the speed of sound.

magnetostrictive delay line

(storage, history)
An early storage device that used tensioned wires of nickel alloy carrying longitudinal waves produced and detected electromagnetically.

They had better storage behaviour than mercury delay lines.
