**3. Conclusion**

The usage of outward magnetic field raises the magnetization for Ni2MnGa and Ni1.85Mn1.15Ga alloys. By applying hydrostatic pressure, which includes Ms and expands the hysteresis width in both alloys. The metamagnetic transition is detected at ambient pressure and suppressed at maximum pressure. The high pressure encourages greater magnetocrystalline anisotropy. Finally, the pressure impact on MCE is reduced in ΔSM for both alloys. In compact of the work, Ni2MnGa and Ni1.85Mn1.15Ga alloys reveal negative and positive PR, when applied to hydrostatic pressure of 30 kbar and 28 kbar. The rate of variation of TM and resistivity pertaining to pressure has been computed and exhibits positive numbers for the two alloys. The ρ<sup>0</sup> and (A) are originated to be reduced with pressure for Ni2MnGa, which exhibit metallic property, merely both rise for Ni1.85Mn1.15Ga, and it may be associated to stationary disorder effects and spin oscillations. These materials have incredible potential interest in sensors and spintronics.
