Evidence of a Hybridized Topological State in Weyl Semimetal/Topological Insulator Mn $_{3 + x}$ Sn $_{1 - x}$ /Bi $_{0.85}$ Sb $_{0.15}$ 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 Mn $_{3 + x}$ Sn $_{1 - x}$ …

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) $_{2}$ Te $_{3}$ - MnF $_{2}$ thin film bilayers

Ryan Van Haren, David Lederman

Thin films of the topological insulator (BiSb) $_{2}$ Te $_{3}$ oriented along the [0001] direction were grown via molecular beam epitaxy on substrates of Al $_{2}$ O $_{3}$ (0001) and MgF $_{2}$ (…

Emergent Magnetic Phases and Piezomagnetic Effects in Mn $_{x}$ Ni $_{1 - x}$ F $_{2}$ Thin Film Alloys

Ryan Van Haren, Nessa Hald, David Lederman

The effect of random competing single-ion anisotropies in antiferromagnets was studied using epitaxial Mn $_{x}$ Ni $_{1 - x}$ F $_{2}$ antiferromagnetic thin film alloys grown via molecular…

Surface state mediated ferromagnetism in Mn $_{0.14}$ Bi $_{1.86}$ Te $_{3}$ thin films

Ryan Van Haren, Toyanath Joshi, David Lederman

A spontaneous ferromagnetic moment can be induced in Bi $_{2}$ Te $_{3}$ thin films below a temperature T $\approx$ 16 K by the introduction of Mn dopants. We demonstrate that films g…
