Autor: Singh, Anupam K., Devi, Parul, Jena, Ajit K., Modanwal, Ujjawal, Lee, Seung-Cheol, Bhattacharjee, Satadeep, Joseph, Boby, Singh, Sanjay

Magnetic skyrmions are vortex-like spin textures, which can be manipulated by external stress or pressure via magnetoelastic effects. Here, we present the observation of isostructural phase transition in a biskyrmion host hexagonal MnNiGa at a pressu

Minimizing hysteresis in martensite phase transforming magnetocaloric Heusler alloys

Autor: Caron, Luana, Devi, Parul, Carvalho, Alexandre M. G., Felser, Claudia, Singh, Sanjay

The large magnetocaloric effect in Heusler alloys showing martensite phase transformation puts them forward as efficient materials for magnetic refrigeration. However, irreversibility of the magnetocaloric cooling cycle is a major challenge for real
