Specific heat of the Skyrmion lattice phase and field-induced tricritical point in MnSi.

We report high-precision measurements of the temperature and magnetic field dependence of the specific heat, C(T,H), across the magnetic phase diagram of MnSi. Clear anomalies establish the Skyrmion lattice unambiguously as a thermodynamic phase. The evolution of the specific heat anomalies, the field dependence of the entropy released at the phase transitions, and the temperature versus field ...

Skyrmion lattice structural transition in MnSi

Magnetic skyrmions exhibit particle-like properties owing to the topology of their swirling spin texture, providing opportunities to study crystallization of topological particles. However, they mostly end up with a triangular lattice, and thus, the packing degree of freedom in the skyrmion particles has been overlooked so far. We report a structural transition of the skyrmion lattice in MnSi. ...

Positron spectroscopy of point defects in the skyrmion-lattice compound MnSi

Outstanding crystalline perfection is a key requirement for the formation of new forms of electronic order in a vast number of widely different materials. Whereas excellent sample quality represents a standard claim in the literature, there are, quite generally, no reliable microscopic probes to establish the nature and concentration of lattice defects such as voids, dislocations and different ...

Electric field induced tricritical point in chiral polarized liquid crystals

2014 We present a Landau theory of the transition between a uniformly polarized smectic C phase and a distorted smectic C* phase in the presence of an electric field parallel to the layers. The field-temperature (E-T) phase diagram is shown to exhibit a tricritical point (Et, Tt). The values of Et, Tt are expressed in terms of observable macroscopic properties of the material.

Electrical probing of field-driven cascading quantized transitions of skyrmion cluster states in MnSi nanowires

Magnetic skyrmions are topologically stable whirlpool-like spin textures that offer great promise as information carriers for future spintronic devices. To enable such applications, particular attention has been focused on the properties of skyrmions in highly confined geometries such as one-dimensional nanowires. Hitherto, it is still experimentally unclear what happens when the width of the n...
