This paper provides a detailed overview of developments in transducer materials technology
relating to their current and future applications in micro-scale devices. Recent advances in …

Application spectrum of shape memory alloys (SMA) is expanding rapidly and
proportionately so is the engineering demand for superior materials. An essential …

The crystal structures of the different martensitic phases observed in a wide variety of Ni–Mn–
Ga alloy compositions have been studied in detail. Similarly to the Ni–Al alloys, the non …

The ferromagnetic Heusler alloys of stoichiometric Ni2MnGa and nonstoichiometric Ni-Mn-
Ga chemical compositions though not containing a noble-metal, indeed, belong to-alloys …

Abstract The Heusler-type alloy Ni 2+ x Mn 1− x Ga exhibits well defined shape memory
properties in a ferromagnetic state, which means that the martensitic transition temperature …

Solid-state cooling based on the caloric effect of phase transformation materials has
attracted considerable interest with the increased demand for energy-efficient and …

We have modelled the phase diagram of magnetic shape memory alloys of the Heusler type
by using the phenomenological Ginzburg–Landau theory. When fixing the parameters by …

Magnetically driven actuator materials, such as the ternary and intermetallic Heusler alloys
with composition, are studied within the density-functional theory (DFT) with the generalized …

In ferromagnetic alloys with shape memory large reversible strains can be obtained by
rearranging the martensitic domain structure by a magnetic field. Magnetization through …

A review is given of experimental and theoretical works concerning the investigation of
magnetic and structural phase transitions and of the magnetocaloric effect in Ni-Mn-X (X …
