摘要：
The magnetic field induced strain (MFIS) in a five-layered NiMnGa single crystal was investigated. Without compressive load, a maximum strain of 5.5% was measured. The hysteresis of the magnetoelastic strain was further characterized by biased minor loops at decreasing magnetic field amplitudes. In contrast to Joule magnetostrictors, the hysteresis widths were found to be independent of the field amplitude which results in a threshold field identical to the hysteresis width for any MFIS.
