Pressure-tuning of the magnetic properties of the Heusler compound Mn2PtGa

We report on the pressure-tuning of the magnetic properties of the Heusler alloy Mn2PtGa. At ambient pressure, Mn2PtGa orders ferrimagnetically below TC≈222 K, followed by a first-order ferrimagnetic to antiferromagnetic transition around TFI−AF≈102 K upon cooling. Magnetization measurements up to 1...

Description
Summary:We report on the pressure-tuning of the magnetic properties of the Heusler alloy Mn2PtGa. At ambient pressure, Mn2PtGa orders ferrimagnetically below TC≈222 K, followed by a first-order ferrimagnetic to antiferromagnetic transition around TFI−AF≈102 K upon cooling. Magnetization measurements up to 1.2 GPa evidence a stabilization of the ferrimagnetic phase, i.e., TC increases while TFI−AF decreases upon application of pressure. The magnetic properties in the ferrimagnetic phase are not altered upon increasing pressure. However, the fraction of the ferrimagnetic phase present in the inhomogeneous antiferromagnetic low-temperature phase increases with pressure.
