Intermartensitic phase transitions in Ni–Mn–Ga alloy, magnetic field effect

The aim of the present study was to investigate the magnetic field influence on the intermartensitic transformations in Ni–Mn–Ga alloy. The temperature dependencies of low field magnetic susceptibility, electrical resistivity ( ρ) and magnetization ( I) were studied in magnetic fields. The measureme...

Zusammenfassung:The aim of the present study was to investigate the magnetic field influence on the intermartensitic transformations in Ni–Mn–Ga alloy. The temperature dependencies of low field magnetic susceptibility, electrical resistivity ( ρ) and magnetization ( I) were studied in magnetic fields. The measurements of ρ ( T ) and I ( T ) were performed in the fields up to 10 kOe. The intermartensitic start temperature M s ′ depends on magnetic field ( H), M s ′ is rising on Δ T = 7 ± 1 K for the field H = 10 kOe . The nature of field-dependent shift of M s ′ was discussed.
