Large magnetically induced strains in [Ni.sub.50][Mn.sub.28.7][Ga.sub.21.3] driven with collinear field and stress
Article Abstract:
Macroscopic measurements obtained from a single crystal of [Ni.sub.50][Mn.sub.28.7][Ga.sub.21.3], which demonstrate a large reversible magnetic-field-induced strain (MFIS) of 4100 ppm when the alloy is driven with quasistatic magnetic fields and fixed compressive stresses applied collinearly along the [001] axis is presented. A thermodynamic model is presented which qualitatively characterizes the decay in MIFS with increasing compressive external load and provides as starting point for the characterization, design, and control of the proposed Ni-Mn-Ga devices.

Preparation and properties of the trivalent-ion doped tungsten bronze [La.sub.x]W[O.sub.3]
Article Abstract:
The production and characterization of lanthanum-doped tungsten oxide, [La.sub.x]W[O.sub.3], sintered samples are presented for 0.05(less than or equal to)x(less than or equal to)0.23. The x-ray diffraction results show that the cubic perovskite phase is stable for x in the range of 0.086-0.21.

Structural dependence of some physical properties of the [Ni.sub.2]MnGe Heusler alloy films
Article Abstract:
Structural ordering of the flash-evaporated [Ni.sub.2]MnGe Heusler alloy films is studied by magneto-optical (MO), optical, and magnetic methods. The optical and MO properties of [Ni.sub.2]MnGe with L[2.sub.1] structure is proved almost the same as those of [Ni.sub.2]MnGa and [Ni.sub.2]MnIn.
