We review the composition dependence of the structural and magnetic properties of the Co-doped Ni-Mn-Ga Ferromagnetic Shape Memory Alloy around the Mn-rich composition Ni50Mn30Ga20. The presence of Co affects the critical temperatures and alters the exchange interactions of martensite and austenite to different extents; by varying the compositon it is possible to tune the critical temperatures and to induce a "paramagnetic gap" between the magnetically ordered martensite and magnetic austenite, thus givind rise to a reverse magnetostructural transformation.
