Domain Wall Spin Torquemeter [PDF]
Physical Review Letters, 2009 We report the direct measurement of the nonadiabatic component of the spin torque in domain walls. Our method is independent of both the pinning of the domain wall in the wire as well as of the Gilbert damping parameter. We demonstrate that the ratio between the nonadiabatic and the adiabatic components can be as high as 1, and explain this high value ...

Strings 2000, 2001 Gravitational properties of domain walls in fundamental theory and their implications for the trapping of gravity are reviewed. In particular, the difficulties to embed gravity trapping configurations within gauged supergravity is reviewed and the status of the domain walls obtained via the breathing mode of sphere reduced Type IIB supergravity is ...

Scientific Reports, 2018 Spin waves (SW) are low energy excitations of magnetization in magnetic materials. In the promising field of magnonics, fundamental SW modes, magnons, are accessible in magnetic nanostructure waveguides and carry information.

Dynamics of chiral domain walls under applied current in cylindrical magnetic nanowires
APL Materials, 2022 The dynamics of two types of chiral magnetic domain walls in magnetic cylindrical nanowires under spin-polarized current are investigated by means of micromagnetic simulations. We show that Bloch point domain walls with chirality identical to that of the

Domain walls in helical magnets [PDF]
, 2012 The structure of domain walls determines to a large extent the properties of magnetic materials, in particular their hardness and switching behavior, it represents an essential ingredient of spintronics. Common domain walls are of Bloch and Neel types in

DOMAIN WALLS ON SINGULARITIES [PDF]
Modern Physics Letters A, 2011 We describe domain walls that live on A2 and A3 singularities. The walls are BPS if the singularity is resolved and non-BPS if it is deformed and fibered. We show that these domain walls may interpolate between vacua that support monopoles and/or vortices.

Gravitational waves from Higgs domain walls
Physics Letters B, 2015 The effective potential for the Standard Model Higgs field allows two quasi-degenerate vacua; one is our vacuum at the electroweak scale, while the other is at a much higher scale.

Runaway dilatonic domain walls [PDF]
, 2010 We explore the stability of domain wall and bubble solutions in theories with compact extra dimensions. The energy density stored inside of the wall can destabilize the volume modulus of a compactification, leading to solutions containing either a ...
