Frustration-driven magnetic fluctuations as the origin of the low-temperature skyrmion phase in Co7Zn7Mn6

Henrik Moodysson Rønnow

In chiral cubic helimagnets, phases of magnetic skyrmions-topologically protected spin whirls-are stabilized by thermal fluctuations over a narrow region directly below the magnetic ordering temperature T-c. Due to often being touted for use in application ...

Melting of a skyrmion lattice to a skyrmion liquid via a hexatic phase

Henrik Moodysson Rønnow, Arnaud Magrez, Fabrizio Carbone, Marco Cantoni, Ping Huang, Thomas Schönenberger

While in 3D materials melting is a single, first-order phase transition, in 2D systems, it can also proceed via an intermediate phase. For a skyrmion lattice in Cu2OSeO3, magnetic field variations can tune this quasiparticle 2D solid into a skyrmion liquid ...

Depersonalization- and derealization-like phenomena of epileptic origin

Olaf Blanke, Lukas Heydrich, Nathaniel Evans

Objective Depersonalization refers to the sensation of being detached from one's body, often associated with feelings of loss of control over one's own body, actions, or thoughts. Derealization refers to the altered perception of one's surroundings that is ...

Matthiessen's rule in MgB2: Resistivity and T-c as a function of point defect concentration

László Forró, Richard Gaal, Neven Barisic, Balazs Sipos

We present the results of a systematic study of the temperature-dependent resistivity and of T-c of a single crystal MgB2 sample as a function of point defect concentration. We have found linear, albeit weak, correlation between the decreasing superconduct ...
