Evidence of a Hybridized Topological State in Weyl Semimetal/Topological Insulator MnSn/BiSb Heterostructures

Ryan T. Van Haren, Gillian P Boyce, Gregory M. Stephen +4

We report magnetotransport evidence of a hybridized Weyl semimetal (WSM) Fermi arc/topological insulator (TI) surface state at the interface of a ferromagnetic MnSn…

Direct Visualization of Relativistic Quantum Scars

Zhehao Ge, Anton M. Graf, Joonas Keski-Rahkonen +9

Quantum scars refer to eigenstates with enhanced probability density along unstable classical periodic orbits (POs). First predicted 40 years ago, scars are special eigenstates tha…

Suppressed weak anti-localization in topological insulator - antiferromagnetic insulator (BiSb)Te - MnF thin film bilayers

Ryan Van Haren, David Lederman

Thin films of the topological insulator (BiSb)Te oriented along the [0001] direction were grown via molecular beam epitaxy on substrates of AlO (0001) and MgF (…

Emergent Magnetic Phases and Piezomagnetic Effects in MnNiF Thin Film Alloys

Ryan Van Haren, Nessa Hald, David Lederman

The effect of random competing single-ion anisotropies in antiferromagnets was studied using epitaxial MnNiF antiferromagnetic thin film alloys grown via molecular…

Surface state mediated ferromagnetism in MnBiTe thin films

Ryan Van Haren, Toyanath Joshi, David Lederman

A spontaneous ferromagnetic moment can be induced in BiTe thin films below a temperature T 16 K by the introduction of Mn dopants. We demonstrate that films g…
