Abstract EN
The structural, magnetic, and magnetocaloric properties of MnCo1-xZrxGe (0.01≤x≤0.04) have been studied through X-ray diffraction, differential scanning calorimetry, and magnetization measurements.
Results indicate that the partial substitution of Zr for Co in MnCo1-xZrxGe decreases the martensitic transition temperature (TM).
For x = 0.02, TM was found to coincide with the ferromagnetic transition temperature (TC) resulting in a first-order magnetostructural transition (MST).
A further increase in zirconium concentration (x = 0.04) showed a single transition at TC.
The MST from the paramagnetic to ferromagnetic state results in magnetic entropy changes (-ΔSM) of 7.2 J/kgK for ΔH = 5 T at 274 K for x = 0.02.
The corresponding value of the relative cooling power (RCP) was found to be 266 J/kg for ΔH = 5 T.
The observed large value of MCE and RCP makes this system a promising material for magnetic cooling applications.
