Ab initio Prediction of Martensitic and Intermartensitic Phase Boundaries in Ni-Mn-Ga
(Amer Physical Soc, 2016)Despite the importance of martensitic transformations of Ni-Mn-Ga Heusler alloys for their magneto-caloric and shape-memory properties, the martensitic part of their phase diagrams is not well determined. Using an ab initio ... -
Decomposition in Ni-Co-Mn-In functional Hensler alloys and its effect on shell-ferromagnetic and magnetocaloric effects
(Amer Physical Soc, 2020)Ni-Co-Mn-In Heusler-based compounds are interesting for their magnetocaloric properties and have been widely investigated for this purpose. For Co compositions more than 5 at% in (Ni100-xCox)(50)Mn25+yIn25-y the material ... -
Effects of supersymmetric CP phases on chargino-pair production via the Drell-Yan process at the CERN LHC
(Amer Physical Soc, 2004)We compute the rates for pp annihilation into chargino pairs via the Drell-Yan process taking into account the effects of supersymmetric soft phases, at a proton-proton collider. In particular, the phase of the mu parameter ... -
Evidence for the formation of nanoprecipitates with magnetically disordered regions in bulk Ni50Mn45In5 Heusler alloys
(Amer Physical Soc, 2019)Shell ferromagnetism is a new functional property of certain Heusler alloys which was recently observed in Ni50Mn45In5. We report the results of a comparative study of the magnetic microstructure of bulk Ni50Mn45In5 Heusler ... -
Exchange bias caused by field-induced spin reconfiguration in Ni-Mn-Sn
(Amer Physical Soc, 2016)Exchange bias is observed in ferromagnetic/antiferromagnetic (FM/AF) layered stacks and in materials with neighboring ferromagnetic and antiferromagnetic granules. The latter is commonly observed in Ni-Mn-based martensitic ... -
Nature of excitons bound to inversion domain boundaries: Origin of the 3.45-eV luminescence lines in spontaneously formed GaN nanowires on Si(111)
(Amer Physical Soc, 2016)We investigate the 3.45-eV luminescence band of spontaneously formed GaN nanowires on Si(111) by photoluminescence and cathodoluminescence spectroscopy. This band is found to be particularly prominent for samples synthesized ... -
Neutron diffraction and symmetry analysis of the martensitic transformation in Co-doped Ni2MnGa
(Amer Physical Soc, 2020)Martensitic transformations are strain driven displacive transitions governing the mechanical and physical properties in intermetallic materials. This is the case in Ni2MnGa, where the martensite transition is at the heart ... -
Phase states and thermomorphologic, thermotropic, and magnetomorphologic properties of lyotropic mesophases: Sodium lauryl sulphate-water-1-decanol liquid-crystalline system
(Amer Physical Soc, 2010)Phase states in sodium lauryl sulphate-water-1-decanol lyotropic liquid-crystalline system have been investigated for different temperature ranges. The dependence of triangle phase diagram types, phase boundaries, and ... -
Quantum Hall effect in a high-mobility two-dimensional electron gas on the surface of a cylinder
(Amer Physical Soc, 2009)The quantum Hall effect is investigated in a high-mobility two-dimensional electron gas on the surface of a cylinder. This special topology leads to a spatially varying filling factor along the current path. The resulting ... -
Segregation tendency of Hensler alloys
(Amer Physical Soc, 2019)Segregation in a series of Ni2Mn1+x(In, Sn, Ga, Al)(1-x) and Mn2Ni1+x(Ga, Al) as well as Ni2+xMn1-xGa Heusler alloys is studied by first-principles calculations. We show that Mn-rich Ni2Mn1+x(In, Sn, Al)(1-x) compounds are ... -
Squark pair production in the MSSM with explicit CP violation
(Amer Physical Soc, 2007)We analyze effects of the CP-odd soft phases in the MSSM on the pair productions of colored superpartners in pp collisions at the LHC energies. We find that, among all pair-production processes, those of the scalar quarks ... -
Unparticle effects in rare t -> cgg decay
(Amer Physical Soc, 2008)In this work the flavor-changing, rare t -> cgg decay induced by mediation of scalar and tensor unparticles is studied. Using the standard model result for the branching ratio of the t -> cgg decay, the parameter space of ...
