Electronic structure in the twinned 10M martensite phase of the Ni49.7Mn29.1Ga21.2 Heusler alloy: experiment and theory
Original language description
In shape memory materials the fine twinned microstructure plays a fundamental role. Here we show that in the martensite phase of Ni-Mn-Ga Heusler alloy, the fine features of electronic structure are not caused by intrinsic electronic changes but mesoscopically different orientations of ferroelastic domains, i.e., twins. The cuts of Fermi surfaces of a (pseudo) tetragonally distorted Ni49.7Mn29.1Ga21.2 Heusler single crystal with a (100) surface orientation were measured using angle-resolved photoemission spectroscopy and compared with first-principles calculations. In this work we demonstrated that the measured photoelectron spectrum was a projection of three separate electronic structures originating from single a-a and two perpendicular a-c ferroelastic domains with a twinned relationship. The twinning results in pseudosplitting of the experimentally observed bands at Fermi level.n
