Magnetocrystalline Anisotropy in a Single Crystal Fe–Ni–Ga Ferromagnetic Shape Memory Alloy*
In order to discuss the advent of the magnetic-field-induced strains for a single crystal Fe22:0Ni51:5Ga26:5 shape memory alloy, the magnetic easy axis in the 14M martensite phase and the magnetocrystalline anisotropy constant K have been investigated. From the data on the spontaneous thermal expansion and the magnetization curves, the magnetic easy axis of the 14M martensite phase was determin...
متن کاملExperimental Study on the Magnetomechanical Characteristics of Ni-Mn-Ga Ferromagnetic Shape Memory Alloy Single Crystals
Magnetic shape memory properties of Ni-Mn-Ga single crystals were characterized by measurement of stress-induced martensite reorientation under constant magnetic fields. Also magnetic field-induced strain as a function of the applied magnetic field under different constant compressive stress levels has been investigated. All the experiments were performed at room temperature in which the sample...
متن کاملMagnetocrystalline anisotropy and orbital polarization in ferromagnetic transition metals
The magnetocrystalline anisotropy energies (MAEs) of the ferromagnetic metals bcc Fe, fcc and hcp Co, and fcc Ni have been calculated by using the ab initio tight-binding method. Disentangling the strong correlation among the d orbitals with the Hamiltonian in the local spin-density approximation, we have investigated the orbital polarizations induced by the Hubbard U and Racah B. The experimen...
متن کاملAnisotropy of Several Properties in a Polycrystalline Fe-Mn-Si Based Shape Memory Alloy
The tensile properties, 7-E transformation and shape recovery have been related to the orientation of tensile axes i.e., along rolling direction(specimen 'A') and toward 45" to the rolling direction(specimen 'B') in a cold-rolled and then annealed Fe-1SMn -10Co-SCr-3Si alloy. It is revealed that the deformation modes of the specimens 'A' and 'B' with respect to tensile axes are not the same; te...
متن کاملMicrostructure and precipitates in annealed Co38Ni33Al29 ferromagnetic shape memory alloy
Transmission electron microscopy was performed to investigate the microstructure and precipitates in the annealed Co38Ni33Al29 ferromagnetic shape memory alloy. Apart from the dendritic secondary phase in the austenite matrix, micron-sized (up to 100 lm) fcc-based precipitates with partial c0 L12 ordering and containing none, one or three {111}p parallel twin planes were found. The orientation ...
