Temperature dependence and temperature limits of magnetic shape memory effect
We study the temperature dependence and low and high temperature limits of the magnetic shape memory effect (MSME) in five-layered tetragonal Ni–Mn–Ga martensite. Using a simple model we show that,Expand

Magnetization changes in Ni–Mn–Ga magnetic shape memory single crystal during compressive stress reorientation
Abstract Magnetization as a function of strain of a Ni 48.5 Mn 30.8 Ga 20.7 single crystal during 9 MPa compressive loading test was obtained by means of vibrating coil magnetometry for differentExpand

Coexistence of ferromagnetic and antiferromagnetic order in Mn-doped Ni2MnGa
Ni-Mn-Ga is interesting as a prototype of a magnetic shape-memory alloy showing large magnetic-field-induced strains. We present here results for the magnetic ordering of Mn-rich Ni-Mn-Ga alloysExpand

The magnetic and oxidation behavior of bare and silica-coated iron oxide nanoparticles synthesized by reverse co-precipitation of ferrous ion (Fe2+) in ambient atmosphere
Abstract The synthesis of iron oxide nanoparticles, i.e., magnetite was attempted by using only ferrous ion (Fe2+) as a magnetite precursor, under an ambient atmosphere. The room temperature reverseExpand

Highly mobile twinned interface in 10 M modulated Ni–Mn–Ga martensite: Analysis beyond the tetragonal approximation of lattice
Abstract The huge strains that Ni–Mn–Ga magnetic shape memory alloys can achieve are usually described in a tetragonal unit cell approximation of a five-layered modulated (10 M) crystal structure.Expand

Activation of magnetic shape memory effect in Ni–Mn–Ga alloys by mechanical and magnetic treatment
Abstract Mechanical and magnetic training decreased considerably the twinning stress of five-layered modulated, approximately tetragonal martensite (5M) of Ni–Mn–Ga and Ni–Mn–Ga doped with Fe, and ofExpand
