Abstract
The magnetostrictive member is formed of a single crystal of an iron-based alloy having magnetostrictive characteristics, is a plate-like body having a long-side direction and a short-side direction, and has a lattice constant of a <100> orientation in the short-side direction larger than a lattice constant of a <100> orientation in the long-side direction.
Claims6
A magnetostrictive member
- formed of a single crystal of an iron-based alloy having magnetostrictive characteristics,
- being a plate shaped body having a long-side direction and a short-side direction, and
- having a lattice constant of a <100> orientation in the short-side direction that is larger than a lattice constant of a <100> orientation in the long-side direction.
A method for manufacturing a magnetostrictive member, the method comprising cutting a crystal of an iron-based alloy and thereby preparing a plate shaped body
- formed of the crystal of the iron-based alloy having magnetostrictive characteristics and having a long-side direction D1 and a short-side direction D2, and
- having a lattice constant of a <100> orientation in the short-side direction larger than a lattice constant of a <100> orientation in the long-side direction.
A magnetostrictive member
- formed of a single crystal of an iron-based alloy having magnetostrictive characteristics, and
- being a plate shaped body having a long-side direction and a short-side direction,
- at least one of a front face and a back face of the plate shaped body having a one-direction processed face with the long-side direction serving as a processing direction, wherein the one-direction processed face has grooves extending in the long-side direction.
