Adaptive modulation in the N i2 M n1.4 i n0.6 magnetic shape-memory Heusler alloy

Devi, P.; Singh, S.; Dutta, B.; Manna, K.; D'Souza, S.W.; Ikeda, Y.; Suard, E.; Petricek, V.; Simon, P.; Werner, P.; Chadhov, S.; Parkin, S.S.P.; Felser, C.; Pandey, D. (American Physical Society, 2018-06-11)

The origin of incommensurate structural modulation in Ni-Mn based Heusler-type magnetic shape-memory alloys (MSMAs) is still an unresolved issue in spite of intense focus on it due to its role in the magnetic field induced ...
Effect of chemical and hydrostatic pressure on the coupled magnetostructural transition of Ni-Mn-In Heusler alloys

Devi, P.; Mejía, C.S.; Caron, L.; Singh, S.; Nicklas, M.; Felser, C. (American Physical Society, 2019-12-10)

Ni-Mn-In magnetic shape-memory Heusler alloys exhibit generally a large thermal hysteresis at their first-order martensitic phase transition which hinders a technological application in magnetic refrigeration. By optimizing ...
Gradual pressure-induced change in the magnetic structure of the noncollinear antiferromagnet Mn3Ge

Sukhanov, A.S.; Singh, S.; Caron, L.; Hansen, T.; Hoser, A.; Kumar, V.; Borrmann, H.; Fitch, A.; Devi, P.; Manna, K.; Felser, C.; Inosov, D.S. (American Physical Society, 2018-06-01)

By means of powder neutron diffraction we investigate changes in the magnetic structure of the coplanar noncollinear antiferromagnet Mn3Ge caused by an application of hydrostatic pressure up to 5 GPa. At ambient conditions ...

Improved magnetostructural and magnetocaloric reversibility in magnetic Ni-Mn-In shape-memory Heusler alloy by optimizing the geometric compatibility condition Open Access

Devi, P.; Mejía, C.S.; Zavareh, M.G.; Dubey, K.K.; Kushwaha, P.; Skourski, Y.; Felser, C.; Nicklas, M.; Singh, S. (American Physical Society, 2019-06-17)

We report an improved reversibility of magnetostriction and inverse magnetocaloric effect (MCE) for the magnetic shape-memory Heusler alloy Ni1.8Mn1.8In0.4. We show that the magnetostriction and MCE crucially depends on ...
Pressure tuning of the anomalous Hall effect in the chiral antiferromagnet Mn3Ge

Dos Reis, R.D.; Ghorbani Zavareh, M.; Ajeesh, M.O.; Kutelak, L.O.; Sukhanov, A.S.; Singh, S.; Noky, J.; Sun, Y.; Fischer, J.E.; Manna, K.; Felser, C.; Nicklas, M. (American Physical Society, 2020-05-05)

We report on the pressure evolution of the giant anomalous Hall effect (AHE) in the chiral antiferromagnet Mn3Ge. The AHE originating from the nonvanishing Berry curvature in Mn3Ge can be continuously tuned by application ...
Reversible adiabatic temperature change in the shape memory Heusler alloy Ni2.2Mn0.8Ga: An effect of structural compatibility

Devi, P.; Zavareh, M. Ghorbani; Mejía, C. Salazar; Hofmann, K.; Albert, B.; Felser, C.; Nicklas, M.; Singh, Sanjay (American Physical Society, 2018-12-28)

The large magnetocaloric effect (MCE) observed in Ni-Mn based shape memory Heusler alloys put them forward to use in magnetic refrigeration technology. It is associated with a first-order magnetostructural (martensitic) ...
Robust Bain distortion in the premartensite phase of a platinum-substituted Ni2MnGa magnetic shape memory alloy

Singh, S.; Dutta, B.; D'Souza, S.W.; Zavareh, M.G.; Devi, P.; Gibbs, A.S.; Hickel, T.; Chadov, S.; Felser, C.; Pandey, D. (Nature Publishing Group, 2017-12-01)

The premartensite phase of shape memory and magnetic shape memory alloys (MSMAs) is believed to be a precursor state of the martensite phase with preserved austenite phase symmetry. The thermodynamic stability of the ...
