When a constant magnetizing field is applied to a Terfenol sample at a fixed temperature, a small fraction (<3%) of the magnetization intensity develops non-instantaneously, Since the strain produced by a constant stress also has a similar behavior, one can infer that the magnetization time dependence is seemingly due to a coupling between the magnetostrictive and the visco-elastic properties of this material.

Abstract
When a constant magnetizing field is applied to a Terfenol sample at a fixed temperature, a small fraction (<3%) of the magnetization intensity develops non-instantaneously, Since the strain produced by a constant stress also has a similar behavior, one can infer that the magnetization time dependence is seemingly due to a coupling between the magnetostrictive and the visco-elastic properties of this material.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
